Just a note to everyone commenting. I may not be completely right, but I’m pretty sure of this.
What I do know is that in videos that I have watched where Brian or one of the other Beach Boys have been interviewed they do give credit where credit is due.
To the likes of Chuck Berry and other black musicians. Brian even gives kudos to The Beatles for Runner Soul and hearing that.
He goes on to say in a video that Paul McCartney said his favorite song of theirs is God Only knows.
Anyway, watch the videos of interviews and some of the making of Pet Sounds to hear the credit given.
