Seeing as everyone seems to have got bored with the McEnroe trivia, the connection between him and MK is that they both own Gibson Les Paul "bursts", generally considered to be the most desirable electric guitars ever built. MK normally plays a 1958 and certainly used to own a '59, don't know if he still has it, McEnroe has a '60 if memory serves, one of a very, very small number of left handed models (Paul McCartney owns one of the other leftys.)
