@bijouxbroussard While I have been unable to uncover anything in my research of any discussions between Chuck and Brian, there was an article that stated Brian wrote the song in honor of Berry and his Sweet Little 16 song, so he knew he was copying the music.
Yes indeed, being a young guy, thrust into the spotlight of a hit single and his other writings and recordings, it probably never even crossed his mind....but again, that puts the burden and the blame on Murry Wilson.

The music industry history is rife with stories of how record producers/companies, and agents screwed over the artists, robbing them of their just royalty payments, and failing to even give them the proper care during their 'tours.' One of the most outrageous is the story of Buddy Holly and the Crickets and their final days on a bus tour, leading to that terrible plane crash.
