Nick Jonas & The Administration are set to hit Musikfest’s Sands Steel Stage on aturdSay night in Bethehem. The group, fronted by the youngest and (arguably) cutest member of the Jonas Brothers, is scheduled to perform after Ocean Grove opens the show at 7 PM. The live chat starts about 8 PM. Saturday. The chat will appear inside the box after it starts, and a transcript will be available after it ends.
