From Spain to Streatham (1959)

Also known as Guitar Craze and the more evocative Hound Dogs and Bach Addicts, this Monitor item (Ken Russell's third for the pioneering BBC arts strand) offers a whistle-stop tour of how Britons are enthusiastically taking up the guitar in all sorts of ways. The instrument's sudden popularity came about as a by-product of the skiffle revival, which led a wide range of people to form bands whose instrumentation was generally as cheap and cheerful as possible. Washboards and comb-and-paper combinations were common, and the only conventional musical instrument was often the humble acoustic guitar.

Unfortunately the movie From Spain to Streatham is not yet available on HBO Max.
