NBC announced Wednesday that the 30 Rock star will have Tom Petty and the Heartbreakers as his musical guest on the May 15 season-ender.

It will be Petty and the Heartbreaker's eighth appearance on SNL — and first live performance since the Super Bowl halftime show in 2008. The band is releasing its 11th studio album, Mojo, on June 15 and will tour this summer.
