Pop Gear/Go Go Mania (the latter being apparently a US-only title for no good reason other than the fact that it wasn’t British) was a brief (one hour, ten minutes) music revue on film, with various Big Beat acts generally faking their way through their 1964 recordings, interspersed with dance numbers.

The song ending as the clip begins is “Tobacco Road,” a John D. Loudermilk tune recorded by the Nashville Teens, who of course were (1) not teens and (2) not from Nashville. The Teens’ second single, “Google Eye”, also a Loudermilk song, missed the bottom of the Billboard Hot 100; however, it does show up later in Pop Gear.
The vaguely oily host, Sir James Wilson Vincent “Jimmy” Savile, OBE, KCSG, died in 2011; a year later, a scandal broke, with Savile accused of multiple acts of sexual abuse. He is now on his way to becoming an unperson.
