The show was called Early Musical Instruments and aired in 1976. There were 6 episodes, each involving Munrow and a group of wan Englishmen making a racket with a certain family of instruments - reed instruments, strummed ones, percussion, etc. Some of them are positively evil looking, such as the gemshorn, a recorder made seemingly out of satan's antlers, or various guitar-like monsters with about twenty strings and nightmarish dragon-like tuning heads. The series was filmed at the beautiful and eerie Ordsall Hall in Salford, known for the ghosts of a White Lady and young girl that have been seen in its staircases. Munrow tragically took his own life at 33, but his legacy carries onwards and upwards -- one of his recordings was on the golden disc accompanying the Voyager spacecraft into the heavens in 1977.
