I was talking to my dad the other day and he told me that apparantly Roger Waters wanted a "Beach Boys sound" for the backing vocals on The Show Must Go On and some of the other tracks on The Wall, and being Roger f'n Waters he obviously just went and asked the Beach Boys to do it.
So according to my dad what then happened was that Brian, Carl, Mike etc stopped work on the self titled album they were working on and learnt the parts Roger had done for them. Roger though thought that in order for them to sing it *properly* he should explain to them the story and the themes of the album to them. Which basically scared them off as Mike decided that it was too far against their image. Which annoyed Brian as he thought the idea was excellent.
So is any of this actually true? Or is my dad just making me an idiot be filling me with false Floyd/Beach Boys trivia?
