Besides Blackpool has David ever been in any other মিউজিক্যাল and can he really sing?

I'm not exactly sure about this, although he "spoofs" গান গাওয়া in DWConfidential at times, and he's done several stage productions, so I assume, he CAN sing, just probably all the other মিউজিক্যাল he's done have been onstage.

Whenever I hear David sing, he's not actually too bad.
