Brian May nails it — the man and the musician. Both men of taste and decency. (A postscript: May mentions Donal, Rory’s brother who talks here about Rory:
We went down to see Muddy and his band playing in a New York club called Ungano’s. The gig was very badly attended by the public, but it was the million dollar audience with Eric Clapton, Steve Winwood, Steve Marriott, Buddy Miles and Hendrix all sitting there.
At the end of Muddy’s set, it inevitably turned into a jam session and Muddy called Rory to the stage, but before he got there, Steve Marriott went up and took the guitar! In typical fashion, Rory just shied away and backed off.
