Nobody will ever know will they?And I am not the person to ask because I was not there.Did The Rolling Stones Murder him? I don't think so,they were finally over him with Mick Taylor and ready to move on.Or really to start over again.The settlement was amicable and no bad press.He was left to get his head and his life back together again and the shame of his death is that he was doing that.He had been destroying himself since late 1965 and further grew to be a great liability to them.He was jealous of the success of the Jagger/Richards songwriting team.But way more than that he just got too fucked up to a point where he was no longer functional.How are you going to drink a bottle of strong brandy eat a mandrax or two, and show up at a rehearsal or at the studio for a session and do anything good?As early as 1966 they wanted Jimmy Page to replace him and he turned them down.His real replacement at that time was the great unsung hero of The Rolling Stones,Nicky Hopkins.The focus of Brian's multi-instrumental ability was done on the mellotron,which Nicky could also play.Many parts that you hear that you think are Brian's are actually Nicky Hopkin's.Kind of a twist of fate as back in the early days their crazy roommate,Jim Phelge,use to call Brian "Hopkin" from his middle name which pissed off Brian to no end.Yet still the sound of the Rolling Stones during this period was focused around Nicky's piano playing,all through Satanic Majesties and Beggars Banquet would not have made it without him.All that he ever received from it was his session fee's.Though they wanted him to join he declined.In his final years he would not even allow a tape recorder to be turned on.It is always sad when a great artist loses their focus due to drugs.
