This comes from a little paragraph I read here: http://www.smh.com.au/news/Music/Come-together-right-now/2005/05/27/1117129889779.html

" In his 1979 memoir All You Need Is Ears, Martin recalls John Lennon freaking out and collapsing one evening in 1967 while making Sgt Pepper's Lonely Hearts Club Band. Martin helped him to the roof to get some fresh air, then feared Lennon might fall off. Martin stayed with Lennon until the crisis subsided."

So, what if John Lennon became an early drug casualty.. either ODing in the studio, or falling to his death from the roof?

Would the remaining Beatles finish Sgt Pepper.. or would it gain status among music geeks as a great unfinished/unreleased album (as per the Beach Boys' Smile album)?

Would the Beatles continue as a band? Would they start performing live again? Who might replace John?
