The 2004 Tony Award-winning musical Avenue Q celebrated its 10th birthday on Wednesday, July 31. A host of the show's alumni, including original cast members Ann Harada, Rick Lyon, Jennifer Barnhart, and Jordan Gelber were on hand for the evening, which included the milestone performance at off-Broadway's New World Stages and a swanky party at Hudson Terrace.

Avenue Q, written by Robert Lopez, Jeff Marx, and Jeff Whitty, opened off-Broadway at the Vineyard Theatre on March 20, 2003, before moving to Broadway's John Golden Theatre, where it officially opened on July 31 of that year. The Broadway production closed on September 13, 2009 and reopened off-Broadway at New World Stages on October 21, 2009.
