Paul McCartney today described the making of his new album, saying: “We just made it up as we went along.”
The ex-Beatle was speaking at an autograph signing of 'Electric Arguments', released under the guise of 'The Fireman'.
The project is a collaboration with record producer Youth.
McCartney said: “This one started to have lyrics and vocals and therefore it developed more as an album.
“It became more like one of my albums so this is why I’m doing a bit of promotion on this.
“It’s great fun to make. We just made it up as we went along.
“We went in with no songs, no words, nothing, and came out later that day with a whole track.
“It was a buzz to work so fast. We did about 13 tracks in 13 days. There was no time to think, which is kind of nice.”
'Electric Arguments' is his third release as “The Fireman” after a 10 year gap since the last album produced alongside Youth (aka Martin Glover).
McCartney said the album title was taken from an Alan Ginsberg poem.
McCartney said that today’s autograph-signing session at HMV’s flagship London store on Oxford Street, had made him feel “nostalgic”.
He said: “There’s not that many record shops – people buying stuff in record shops – anymore, so it’s a bit nostalgic.
“The main thing is to actually meet the people who buy your records and you get some amazing stories.
“You’re doing a signing and then someone says ’I have just flown in from New York’. She drove from Philadelphia. That is why I do it.”
He then joked to reporters: “Being in a record store is lovely. I’m always tempted to shoplift,” but he swiftly added: “No I’m not, no I’m not. I wouldn’t do that.”
The musician went on to say that he was considering doing more live shows in 2009.
“There are no plans for touring but we are thinking about it.
“We have not got any set dates at the moment. There are a lot of nice offers next year so I’m looking at seeing how I can do it.
“I’m hoping to get out there. It’s what I do and I love it.
“It really is great when you have got an audience in front of you and you’re singing and you can tell they like it.
“You’re not in a vacuum anymore like you are in a record studio,” he said.
He said he will be having a “chaotic but wonderful” Christmas Day with his brother’s family and his own children and grandchildren.
Many fans, who had queued overnight earlier this week to be allowed entry into the event, cried after they had met their idol.
Dani Calder, a 21-year-old politics student at the University of Stirling, was first in line.
She said McCartney “looked a little scared” when he saw the Wings tattoo on her arm.
She added: “He’s an absolute legend. I wanted to meet him again.”
Another fan, Peter Warren, 48, from Winchester, said: “I thanked him for 44 years of pleasure. It’s important when your hero is a decent man. He was a role model to me.”
Eleanor Wilde, 26, from Liverpool, believed she had no choice but to turn up today.
She said: “If you find out he’s doing a signing, you have got to make an effort and come.
“He said ’Happy Christmas’. He’s dead lovely.
“Of all the people who have created music throughout the years, he’s the main one. It means the world.”
