Steptoe and Son S06E02 - Come Dancing

Harold wants to win the affections of a woman called Jean who is a great fan of ballroom dancing but is pessimistic because he has two left feet. Albert, on the other hand, was once very light on his feet so he teaches Harold the basic steps with which to impress Jean. Unfortunately Albert has been leading all the time and Harold going backwards so he ends up only learning the woman's steps.
