If you walk out the front of the Lyceum theatre to exit you have to go around the block to the back of the theatre for the stage door. I was there the other day and there were only about 6 people waiting, it was the Saturday matinee. I took my time as I wasn't really planning to wait for him, so I got there about 10 minutes after the show let out and he came out about 5 minutes later, signed for everyone who was waiting and was incredibly charming and polite and nice.
I had a black sharpie on me only so he just signed across the yellow playbill logo at the top.
And hang on, when did you win the discus?
