Alongside the late-model Marleys and Lennons in the pantheon of promising pop progeny, we might one day also find singer-songwriter Harper Simon — son of Paul, heir apparent to Graceland and all its accompanying royalty checks, since he’s specifically mentioned in the second verse of the title track — whose first high-profile gig was singing “Bingo” alongside his pops on a 1976 episode of Sesame Street. (Locally and somewhat more recently, he was also bizarrely singled out during the closing of IS Venue back in September.)
