Messrs. Bruce and Baker famously loathed each other throughout their tenure in Cream, although to be fair, Ginger is renowned for loathing anyone breathing the same air as him!
I know GB suffered from heroin addicition, but seems to be clean and sober now - and enjoying his horses. It's unlikely he will be able to play again, his arthritisi is too advanced, and that is a great shame, he is a wonderful player.
Hint - if you ever speak to him, always refer to him as a 'jazz drummer', and make sure you bone up on his major hero Phil Seaman - Ginger thinks not knowing who Phil Seaman is deserves a punch up the bracket!
