I will confess that, although I watched Doogie Howser as a kid, I really didn't fall for Neil Patrick Harris until I heard him sing the role of Toby in the 2000 Lincoln Center Concert version of Sweeney Todd. What a voice. A couple of years later, I stumbled across a studio recording of him singing the part of Charles in Sondheim's seldom heard television musical, Evening Primrose. Since then I've collected as many of his recordings as I've run across: Assassins, Batman: The Brave & The Bold (yes, it's a musical), Dr. Horrible's Sing-Along Blog (a work of genius by my hero Joss Whedon), Commentary! The Musical (another Joss Whedon production), and of course his Glee appearances (singing with Matthew Morrison - could it get any better?).
"My Eyes" from Dr. Horrible's Sing-Along Blog:
I also saw Neil in Proof on Broadway in 2002. He played opposite Anne Heche and Len Cariou as Hal, a young grad student who discovers a groundbreaking proof that he attribues to his mentor Robert (Cariou), but which could be the work of the professor's daughter Catherine (Heche). Hal tumbles into a romantic relationship with Catherine as she grapples with the complicated world of genius, mathematics and mental illness. His performance was startling in its intensity, energetic and real. And it left me wanting to see more of his theater work.
