The Lucy Show: Lucy and Carol in Palm Springs (1966)

Synopsis
In the concluding episode of a two-part story, Lucy's roommate Carol Bradford (Carol Burnett) is hired along with The Vagabonds to perform a musical act at an upcoming Palm Springs golf tournament. When she is invited to accompany Carol to the gig, Lucy (Lucille Ball) feigns illness so she can skip work. Upon her arrival at Palm Springs, Lucy is fixed up with a date with handsome movie actor Collin Grant (Dan Rowan)--who happens to be the golfing partner of Lucy's boss Mr. Mooney (Gale Gordon). Carol, Lucy and The Vagabonds (including an uncredited Joe Pesci!) perform "Lazy River" and "The Hukilau Song." ~ Hal Erickson, All Movie Guide
