Here is one of the rare music videos we stumbled upon recently. It is by Pauline Murray and the Invisible Girls who released it in 1980. "Mister X" was the second single which was also appeared on their self titled debut album released during the same year.
The single was backed by "Two Shots" and it was written by Martin Hannett. Sadly there is no info about the video. Poor quality fragment, but still great to have it around on YouTube.
