Members of Penn State University's classically trained Concert Choir will get to take the stage alongside Mick Jagger and the Rolling Stones when the band plays Pittsburgh's Heinz Field.
The legendary rock group often invites a local choir to sing backup vocals for the band during concerts, famously for the opening of the song "You Can't Always Get What You Want."
Penn State will bring 24 singers to Saturday's show, a group largely made up of undergraduates and a few recent graduates.
Choir director Christopher Kiver says it's a different turn for his group to be playing music commonly found on iPods.
The choir will have one rehearsal with the Stones the afternoon of the concert before making its rock `n' roll debut.
