After six years on Broadway, the Tony-winning musical Avenue Q will deliver its final performance on Sept. 13, producers announced Monday. The somewhat raunchy puppet-driven show will have played 2,534 performances and 22 previews, becoming the 20th longest running show in Broadway history. (It will pass The Producers on Aug. 13.) The Off Broadway transfer has proven to be an unlikely success story, notoriously beating out Wicked for the Best Musical Tony; the $3.5 million production has also returned $23.5 million to its investors. In addition, Avenue Q spawned a national tour, a short-lived Las Vegas run, and a London production that reopened at the Gielgud Theatre on June 1.
