The YHA Shop on Deansgate was a regular lunch time meeting place for Manchester climbers in the late 70s. Brian Cropper, who was the manager at the time, had the foresight to snap the regulars of the day. I received these two shots from Brian in a round about way. I'm still in touch with Marcus Tierney and as a result of the picture I made an effort to contact Tony Dilger.
