The Beatles. No one else even comes close.

My choice as well. But Fleetword Mac is a clean second.
Loved Fleetwood Mac. Went to see them in Miami many years ago. So much pot being passed around that by the time they came on, I was pretty much out. I remember Stevie Nicks singing Rhiannon and after that - nothing. LOL
No pot at the concert I went to last night but a lot of beer and wine.
