Hosted and co-produced by Justin Guarini ("American Idol," Wicked), the event gives Comic Con attendees and Broadway fans the chance to perform with a live karaoke band and have a front-row seat to live performances by Guarini, Tony Award winners Lena Hall (Hedwig and the Angry Inch) and James Monroe Iglehart (Aladdin) and Tony Award nominee Ramin Karimloo (Les Misérables).

"Clear Channel Spectacolor is proud to be partnering with New York Comic Con, Super Week, and Playbill to offer these advertising partners a memorable way to connect with their consumers," said Harry Coghlan, president of Clear Channel Outdoor, New York, in a statement. "Celebrity Karaoke is a uniquely New York entertainment experience for Comic Con attendees that gives theatre fans the opportunity to perform alongside Broadway's superhero talent."

In anticipation of the Epic Evening with the Stars, the #MyDreamDuet contest will give fans the chance to sing alongside Guarini, Hall, Iglehart and Karimloo live at the concert.

To enter, hopefuls are asked to record a performance of themselves singing a song from the show in which their possible duet partner stars in — Wicked for the chance to sing with Guarini, Hedwig for the chance to sing with Hall, Aladdin for the chance to sing with Iglehart and Les Miz for the chance to sing with Karimloo — and upload it to YouTube. Performances should be under three minutes and submitted to Playbill and Clear Channel Spectacolor via Twitter, using the hashtag #MyDreamDuet and the Twitter handles @playbill and @CCSpectacolor.

Hopefuls should be able to provide their own transportation to New York City's Hard Rock Café in Times Square Oct. 6, and submissions will be accepted through Sept. 27 at 12:01 AM ET. Four winners will be announced Sept. 29, and they will perform at the Epic Evening with the Stars Oct. 6. Performances will be judged by two-time Tony Award-winning producer Darren Bagert (Side Show, Of Mice and Men), Tony-nominated theatre and film producer Carl Levin (Rock of Ages) and Playbill editor-in-chief Blake Ross.

The event will include red carpet arrivals at 5:30 PM, followed by the live show from 7-10 PM. Tickets can be purchased through TicketWeb by clicking here.
