great musician's audio systems

A Naim dealer recently told me that Charlie Haden (bassist for Ornette Coleman in early 60's) had an all Naim rig with a Linn TT. I know for sure that Keith Richards and Ron Carter both own Tetra speakers (the manufacturer lets that be easily known). I have been curious if any of my fellow audiophiles might know what the audio systems of other great musicians were like. And if anyone knows of past musican's rigs (Pablo Casals, Jimi Hendrix, whatever) this should be a very interesting discussion indeed.
