W.W. and the Dixie Dancekings (1975)

W.W. is a happy-go-lucky crook who makes his living robbing gas stations through the drive-up windows. The Dixie Dancekings are a country music band trying to get their first big break. W.W. crosses paths with the Dixie Dancekings when he hijacks their car (and them) to help him rob a bank. At first, the band resists. However, when they discover how much money they make, they begin helping out voluntarily in order to finance their big break. At the same time, W.W. takes a liking to them and uses his natural charm and smooth-talking ways to help them start down the road to stardom.
