"In 1977, I fancied doing a Scottish bagpipe song, so I wrote Mull Of Kintyre. The people who hated it were p****d off with me.
"Of course, it didn't help that it came out at the height of punk rock. But what should I have done at that time? Stuck a safety pin through my nose and done some bonkers punk song?
MY attitude is really: 'Sod you. You think Mull Of Kintyre is crap - you try writing something like that.' I do get annoyed at having to justify myself.
It would have been all wrong for Paul to "write" a punk song. Wrong era, wrong mindset. There is a "play it loud, play it wrong" asthetic to Helter Skelter. There is an element of early 60s R&B tinged garage punk in some "unreleased" Beatles songs like "Leave My Kitten Alone".... but largely the Beatles were a pop band that went psychedelic, formed a publishing company for other artists, watched as Woodstock passed them by, and fought for more representation on their albums.
They knew they all had songs to contribute. They didn't want every release to be a 2-record set like the White Album (and the projects would not have had the cohession of Rubber Soul or Revolver).
