Sir Paul McCartney had forgotten how to play SGT PEPPER'S LONELY HEARTS CLUB BAND prior to last month's (JUL05) Live 8 concert, and asked U2 guitarist The Edge to help him find the right notes.
The former beatle had never played the classic song live before, and he was terrified of making an embarrassing mistake on the big day.
He says, "I needed to re-learn Sgt Pepper for Live 8. I'd never sung it (live) before.
"Me and The Edge couldn't figure out the guitar riff. I had the guitarist from my band helping out too, but we eventually sorted it out."
