I always thought that "If I Fell" (in love with you) was the 1ST song they wrote that i couldn't hum along to, due to the complex vocal harmonies. even though i wasn't much of a music critic at the time, i began to feel that this was no ordinary pop group, not just due to the large quantity of songs they came up with, but now with songs that required considerable knowledge of complex chord structures. (yeah, yeah, yeah), the beatles were pretty darn great.
