Dan Radcliffe, along with HP co-star Helena Bonham Carter (Bellatrix Lestrange), will join several other celebrities on
American Idol Gives Back, a fundraiser for childhood poverty in the U.S. and Africa. The show will air on April 24 and 25.

DR.co.uk UPDATE: Jenna at
DR.com has added that whilst Dan will be contributing to this event in some capacity, he will
NOT be on the show in-person (as he's performing in
Equus virtually every night, this seemed fairly obvious to begin with.)
Mugglenet report that instead a pre-recorded video made by Dan will be shown.
