... but I think -21.12.79 Tjens Couter, Herenthout, Belgium- is wrong. Tjens Couter was in fact a Belgian 70's band and not the name of a venue... Maybe the date and Herenthout are correct (and performed The Cure as support act for Tjens Couter???). I'm only guessing. The most popular (maybe the only!?) club in Herenthout (which is a very small town) was Zaal Lux.
