Top billing Once best known for playing Hannah Montana's best friend, actress and singer Emily Osment is now up front as a dynamic performer of high-energy dance-pop (her infectious "Lovesick" is an early entry into the song-of-the-summer sweepstakes). She headlines the Fam Jam, with rising Radio Disney star Cody Simpson and Tim Urban of American Idol fame, at 1 p.m. at the RiverStage at Penn's Landing, Columbus Boulevard and Chestnut Street. Admission is free. Call 215-922-2386.
Time shticks on In his one-man show Long Story Short, former Saturday Night Live newsman Colin Quinn goes through the history of the world, from the ancient Greeks to the Jersey Shore guidos (or as the tag line puts it more succinctly, "from Socrates to Snooki") in about 75 minutes. It all boils down to simple conflict, according to Quinn: Tough guys vs. smart guys, and there are modern parallels that make the Inca empire and the Great Wall of China seem contemporary. The original Broadway production was directed by Jerry Seinfeld, and we figure there's no reason the Philadelphia Theatre Company production would mess with that. The show goes on at 7 p.m. Sunday at the Suzanne Roberts Theatre, Broad and Lombard Streets, and continues with shows at 8 p.m. Tuesday; 8 p.m. Wednesday and Thursday; 7 and 10 p.m. Friday; 2, 7, 10 p.m. Saturday; and 7 p.m. next Sunday. Tickets are $51 to $65. Call 215-985-0420.
