"
I Know There's an Answer" is a song by American
rock band the Beach Boys, taken from their 1966 album
Pet Sounds. It was composed and produced by
Brian Wilson in lyrical collaboration with bandmate
Mike Love and the group's road manager Terry Sachen. The song was written as a reaction to Wilson's experiences with
lysergic acid diethylamide (LSD), as he explained, "I had gotten into that kind of thing. I guess it just came up naturally."
