File:Paul McCartney & Wings - Mary Had A Little Lamb (Official Music Video, Remastered)

In early June Wings popped over to the BBC TV Studios and filmed a variety of promo videos for their new single "Mary Had a Little Lamb". They filmed four promos in all with, presumably two for UK/Europe and two for America. The first promo known as the "Barn Version" (cos it was shot in a mocked-up barn with real chickens) was originally broadcast on "Top of The Pops" on June 29th 1972.
