The Beach Boys
Aw come on, you mean these surf jockeys that took London by storm in 1966 and in the NME contest that year pulled #1 band right from under John Lennon's beak? And all this while Brian stayed home alone and began his second sonic masterpiece, Smile - (the first being Pet Sounds which was the inspiration for Sgt Pepper)
Nah, no way these dudes could come anywhere close to being "better than the Beatles". They were just that other band on Capitol Records. /s
