Sir Paul McCartney has said his new album with side project The Fireman could ruin his whole career.

The former Beatle previewed 'Electronic Arguments', which has been produced by Youth, for journalists in London this afternoon (October 9th).

The album features thirteen tracks written by Sir Paul and is the first Fireman album to feature vocals. Each track was recorded in thirteen days over the period of nearly a year.

Sir Paul told reporters that Youth had encouraged him to improvise, which he said “could be a terrible mistake”.

“It could ruin my whole career. This could be the most embarrassing moment of my life,” he said.

"Having written so much over the years, when I'm improvising I think I can spot what works."

'Electronic Arguments' is released on November 14th. Reports have claimed that one of the songs on the album is inspired by Sir Paul's former marriage to Heather Mills.
