These second two images are amazing and the source was part of this band so they are genuine.
These images are of a band rehearsing in 1964 in what was one the Morgue Skiffle Cellar in Balgownie. You can see it was redecorated and that there was a window but the stage that Ernest, Rory and Johnny is visible. To have any photographic evidence is unheard of so these are amazing.
I'm not so sure that was a window in the Club. If it was a celler it would be underground. Maybe a poster board with paper lists attached.
I didn't think the Morgue lasted until '64? I thought it was done when the cops arrived because people complained the groups were too loud and they didn't have a permit after a few weeks of operation in '58.
OK re-reading it they were just rehearsing in the place where the original club was.
