Rhythm of the Comics: Comedians Chevy Chase and Steve Martin took turns holding down a giant Casper the Friendly Ghost balloon as the pair helped singer Paul Simon make a new music video. The 4 1/2-minute video will feature the comics clowning amid the floats and baton twirlers in the Jaycees Christmas parade in Richmond, Va. The video will accompany a single from Simon’s latest album, “Rhythm of the Saints.” Simon’s album is No. 5 on Billboard magazine’s album chart.
