Our local PBS station recently had a fund-raiser - one of the shows being a compilation of clips from the British show “Ready Steady Go” (roughly equivalent to “American Bandstand”). The clips seemed to be mostly from the 1963-65 era, featuring popular British (and a few American) groups and soloists, such as the Beatles, the Rolling Stones, the Four Tops, etc.
Most lip-synched their songs, but what confused me is that when the Beatles appeared, there was no screaming (or other reactions) from the numerous females dancing (or just watching). Did they simply turn off the sound and “paste” the lip-synched soundtrack over the silence?
Here is part what was shown on the PBS show (Beatles are near the start).
