15th July 1978: Eric's, Liverpool (afternoon performance)
Supporting Rich Kids
Rich Kids played two performances, a matinee and an evening show.
Joy Division supported Rich Kids for the matinee show only.
Germs, who later became Glass Torpedos, supported in the evening.
This information came to light in 2016.
At this stage Joy Division weren't big enough to get a namecheck on Eric's monthly flyer:
Thanks to Steve for the flyer scan from his Flickr
