A friend just emailed me a link to this memorable find by the pop-culture blog Bedazzled: A delightfully square medley of Beatles tunes sung by a cast including Bing Crosby, Gwen Verdon, Bobbie Gentry, Engelbert Humperdinck, and Dick Shawn (best known as the brain-damaged hippie who gets Hitler's singing part in the original The Producers) on a 1969 episode of the TV variety show Hollywood Palace. Here's a link where you can download the clip.
