If there is a souvenier program, I'll get that signed on the front cover. If not, then I'll get the playbill signed.
If I'm a big fan of the performer that's in the show I'm seeing, then I'll bring ONE other thing from another show to get signed if it isnt signed already. For example, I had Denis O'Hare sign my sweet charity playbill (because there wasnt a program at the time) and he was delighted to see that I had my assassins cd booklet with me for him to sign.
