This is one of the first ever moonwalks on film
Bill Bailey tapping to a rather quiet instrumental version of the Larks' hit "The World is Waiting for Sunrise" performed by the Paul Williams Quartet.
He's the brother of singer Pearl Bailey, but he has nothing to do with her signature song "Won't You Come Home Bill Bailey" which is a very old standard dating back to 1902.
Bill's frequently credited with "inventing" the "moonwalk" because of a tapdancing move called "backslide" which he does in this filmed performance.
