If you want to see Daniel Radcliffe sing, tune in early to the Tony Awards.

The "Harry Potter" star says he'll perform the song "Brotherhood of Man" from his Broadway show "How to Succeed in Business Without Really Trying" early in Sunday's telecast.

Says Radcliffe: "I think we're one of the first, if not the first."

Radcliffe revealed the news Monday while welcoming hundreds of New York City students as they made their Broadway debuts — performing routines from musicals on the Majestic Theatre stage.

Radcliffe was passed over for a Tony nomination, but says he's pulling for co-stars John Larroquette and Tammy Blanchard, who are up for awards.

"If John won it would be just amazing," he says. "Only because I have a lot of scenes with him."
