The Beatles?

Paul got into a fight with the other 3 (the song was about a LSD trip and he was the only one who hadn't done it) and left the studio. George played bass on that track, I believe it's the only Beatles song that Paul isn't on. His death allegedly occurred after he left that night.

Lovely RIta, meter maid, is actually about his death apparently

They were skilled pop tunesmiths. They also had a good ear for incorporating then-current trends into their work (while still sounding like "The Beatles"), and they were relatively open to new ideas.

ayy, nice reference
