Goat, I don't know about Madonna's hairdresser, but I can attest to the fact that Keith does in fact know everyone he claims to know and I, who actually don't care if I ever meet anyone within the ranks of stardom or political importance ever again (been there - done that!) have been introduced to many by Keith on numerous occasion.
I personally don't know Madonna's hairdresser but I know a good number of her entourage (had to look that one up) and I do plan to intro them to Keith shortly on a very important occasion which I am not at liberty to disclose at present.
BESIDES - Keith will never catch up with me in the "Knowing People" department. At an early age I set a goal to meet as many good people as possible before I leave this big blue marble and I'm sure that one day we will be shaking hands as a result of Keith's introduction. You can count on that!
