Russell Brand and Jonah Hill will get to taste real-life rock stardom on Monday night (24May10) when they stage a one-night-only concert to launch their new movie GET HIM TO THE GREEK.
As Infant Sorrow, the duo will hit the stage at Los Angeles rock mecca The Roxy and perform songs from the film.
Brand's band features British rocker pal Carl Barat and other "surprise guests".
It is not known if the funnyman's fiancee Katy Perry will perform.
