Gary Yudman

Hi I'm new here and just signed up. I am 18 years old and have been a Pink Floyd fan since I was 9. Sorry if this has already been asked. But my question, is Gary Yudman (the Master Of Ceremonies for the majority of 1980-1981 Wall tour) known for anything else unrelated to Pink Floyd and that role? And does anybody know what he's done since 1981 and how the band knew/chose him to being with? I always loved that segment on the Nassau Coliseum and Earls Court DVDs where the joke was testing the crowds' patience so I've always been curious.
