Not everyone hates Gordon Brown. “He listens to our music every day,” says his friend, the Bee Gee Robin Gibb. “Gordon likes our music and I like Gordon. I was with him at a dinner recently” – Gibb says this with the air of a man for whom dining with the Prime Minister is all in a day’s work – “and he was asking: who is creating the big song catalogues of today? The answer is no one. Record companies today don’t see the need for creating big catalogues because that involves investing in careers, which they are no longer doing. But great songs are the backbone of music. They transcend the artist and the record and become part of the culture.”

It is not hard to see why Gibb is passionate about the craft of the pop song. The Bee Gees, the band he formed in his teens with his late twin Maurice and their elder brother Barry, are one of the most successful acts of all time. A fair chunk of the world’s population can sing along to Tragedy, Jive Talking and Stayin’ Alive.

The Bee Gees recently became the first band to be made fellows of the British Academy of Composers and Songwriters, for which the flagship event is the Ivor Novello Awards next Thursday. Since the ceremony is all about celebrating the art of the song, Gibb is one of its most vocal supporters.

“The Ivor Novellos [are] the beacon of the songwriting establishment in Britain,” says Gibb, a remarkably thin man with a gentle if slightly cadaverous air about him. “I come from an era when artists wrote their own songs, when people like Paul McCartney and Elton John created a huge body of work. We are in real danger of losing that tradition.”

Gibb lives in a 1,000-year-old former monastery in Oxfordshire with grounds equivalent to a reasonably proportioned London park. And he counts prime ministers past and present among his friends. “Tony Blair is a great friend,” Gibb says of our former leader, who took a holiday at Gibb’s Miami house in 2007. “I respect him tremendously. In this business you have friends from all backgrounds, including prime ministers and princes, and we get on like a house on fire.”

Brown likes the Bee Gees music, Gibb says, “because it talks about human relationships and experience, rather than specific events, and reaches out across the decades.” Brown has told Gibb: “Your music is absolutely timeless.”

Gibb is in fine form, talking rapidly in a Mancunian twang. Interviews have suggested that he feels the Bee Gees are not taken as seriously as they should be – there was the incident in 1998 when all three stormed off the set of Clive Anderson’s television show after the presenter made a joke about their once being called Les Tosseurs – but if this is still the case, he’s not showing it.

“We’re not just performers but also songwriters, which is the important thing,” he says. “I love Mozart because of his emphasis on melody, but in his time he wasn’t taken seriously at all. Now nobody listens to Mozart and says, ‘That’s so 1780s’. What you are left with is the music.”

“The music” has been Gibb’s saviour. He grew up in a poor family in Manchester until he was nine, when the family moved to Australia. The Bee Gees formed soon after, inspired by the broad variety of music they heard on Australian radio. “We didn’t have a pot to piss in when we were growing up – my dad couldn’t hold down a job – but we didn’t feel we were missing out because we had a lot of fun writing songs. We would hear our favourite bands on the radio and then try and write in their style, pretending that we were coming up with their next hit. We never thought about fame or anything like that.”

Does it bother him that the pop song is frequently dismissed as teenage trash? “That’s just an attitude and it doesn’t impact on the quality of the music,” he replies. “Writing a simple melody that people remember and that can be interpreted in different styles is one of the hardest things to do. Look at Islands in the Stream. We wrote that as an R&B tune but Dolly Parton and Kenny Rogers turned it into pure country. A lot of classical composers worked in the same way. It’s rumoured that Beethoven sat in Bavarian taverns and stole melodies from travelling folk singers, so concepts of what is high or low art are irrelevant.”

The Bee Gees were writing songs at a farmhouse in France in 1976 when their manager, Robert Stigwood, approached them to provide music for an adaptation of a short story by Nik Cohn called Tribal Rites of the New Saturday Night. “We weren’t at all sure about it,” Gibb says. “It’s a dark film about what was really going on in New York at the time, and it has gang rape, suicide . . . Robert Stigwood came over to listen to our new songs while crickets chirped and cows mooed in the background, and he talked about this thing called disco we had never heard of, and between us we came up with this marriage of film and music that eclipsed everything. It was a low-budget film with no marketing at all and yet it captured imaginations.”

At the height of their powers the Bee Gees couldn’t help but write smash hits. “We wrote Tragedy and How Can You Mend a Broken Heart? in one afternoon at our house in Addison Road in Kensington. Both went to No 1, so that wasn’t a bad afternoon’s work,” he says. “We would sit around with a tape recorder and a keyboard and bash out ideas, and I think it worked because we had fun. If you think too hard about what you want from a situation it never works. The secret is to enjoy it.”

Since Maurice died in 2003 a return to that golden age of fraternal hitmaking is impossible. But Robin and Barry are in talks about writing a musical based on their back catalogue, and there are always mainstream pop stars ready to look to a Gibb brothers composition for material – Barbra Streisand, Diana Ross and Destiny’s Child are a few that have already done so.

Gibb’s main concern for the future is that the songwriting culture is in danger of dying out. “Programmes like The X Factor turn the song into a vehicle for celebrity rather than the other way round,” he says. “Our whole lives have been made up of projects that went into creating a catalogue of songs that the world has embraced. I just wish that the world today [was] more like the world we started out in.”

The 53rd Ivor Novello Awards, is the flagship event for the The British Academy of Composers & Songwriters. The awards take place on May 22 2008. See the winners at www.theivors.org
