It's something an Australian actor could only have dreams (or nightmares) about - appearing in the same show, week in, week out since January 26, 1988. According to Playbill, that's been the fate of Broadway Phantom of the Opera stars George Lee Andrews, Richard Warren Pugh and Mary Leigh Stahl, who have been with the production from the word go. Phantom is now the longest-running show on the Great White Way and has been the biggest generator of income and jobs in American theatre.
PS: I met composer Andrew Lloyd Webber once. I literally bumped into him on the opening night of Phantom in Melbourne about 15 years ago. All I could do was shake his hand and say "Congratulations".
