I haven't seen POTO since '91, but of the three Phantoms I've seen Michael Crawford was the best. His voice, while not angelic, is creepy and added to the tension, and his physical grace was astonishing. His performance was all the more amazing considering he had nothing to work with given Sarah Brightman's lack of presence as Christine.
Chris Groenendaal sang it beautifully and was a very moving Phantom.
Marc Jacoby was sinister and heavy handed.
I haven't seen it since then, so I have no idea about all of the other men who've played the part. But those are my choices based on who I've seen.
Cheyenne Jackson tickled me. AFTER ordering SoMMS a drink but NOT tickling him, and hanging out with Girly in his dressing room (where he DIDN'T tickle her) but BEFORE we got married. To others. And then he tweeted Boobs. He also tweeted he's good friends with some chick on "The Voice" who just happens to be good friends with Tink's ex. And I'm still married. Oh, and this just in: "Pettiness, spite, malice ....Such ugly emotions... So sad." - After Eight, talking about MEEEEEEEE!!! I'm so honored! :-)
