As far as the big Actor's Fund of America benefit concerts that they do every year, I think that they started with Dreamgirls in 2001. They've been:
2001: Dreamgirls
2002: Funny Girl
2003: Chess
2004: Hair
2005: On the Twentieth Century
2006: Best Little Whorehouse in Texas
Pippin was a World AIDS Day benefit, which isn't done by the same organization.
Edit: Aaand someone beat me to it.
