Harvey was played by himself. Ironically, he refused to play himself in the stage version because of contractual disputes. Go figure. Here's who knew:

Neil
Melinda
Nancy K (the K stands for Kosuke Fukodome)
Stephen K (the K stands for Koskie What?)
Mike K (the K stands for Kerry Wood Is Much Easier To Pronounce)

Way to go, all of you.
