In a programme first broadcast in 1981, Angela Rippon explores the world of tap-dancing, tracing its roots from Harlem, New York, and from clog-dancing in Lancashire. She also looks at the revival of tap on Broadway in her search to discover what it takes to become a professional dancer today. She talks to Ann Miller, the fastest tapper in the world, finds out what a dancer's life is like backstage and sees for herself the agony of auditions. Finally, she takes a few tap lessons from the Happy Hoofer choreographer, Lionel Blair.
