Shang-a-Lang was a children's pop music TV series starring the Scottish band, the Bay City Rollers. It was produced in Manchester by Granada Television for the ITV network and ran for one 20-week series in 1975. It featured the band in a number of comedy sketches and performing their songs to a live studio audience made up of their teenage fans. This resulted in chaotic scenes at times as some members of the audience attempted to run onto the studio floor to meet their heroes, resulting in security officers having to forcibly restain or even eject them from the studio. The show's theme song "Shang-a-Lang", was a hit single for the group, peaking at number 2 in 1974 in the UK.
