Joss Whedon Presents Dr. Horrible's Sing-Along Sing-Along

The online musical phenomenon is encouraging you to sing along for a good cause. On Sept. 21, Joss Whedon, writer and creator of the wildly popular Dr. Horrible's Sing-Along Blog will host a sing-along screening.

Whedon will attend the event being called "Dr. Horrible's Sing-Along Sing-Along," and will conduct a Q&A session afterwards featuring as-yet-unnamed special guests. (Is anyone else hoping that the Doctor Formerly Known as Doogie Howser makes a surprise appearance?)

The event will take place at the Peter Jay Sharp Theatre in New York, and proceeds will benefit 826NYC, a non-profit organization that encourages kids to develop their creative and expository writing skills.
