Drew Altizer passes along these awesome pictures of Eric McCormack (Will from Will and Grace) singing his heart out at the American Conservatory Theater Ruby Jubilee last week, celebrating the ACT's 40th year.

Alas, Drew reports that scheduled guest Annette Bening didn't make it, but a source who was there tells us that Nancy Pelosi did. Pelosi missed the performances, but was surrounded by an entourage and mingled through the night with a big smile on her face.

Check out the rest of Drew's pictures from the evening after the jump, or click here. Thanks, Drew!
