Remember it well.
My then girlfriend (now wife) was a trainee nurse at the royal.
Every week free entry tickets would be placed in the nurses home, my wife always used to try to get a couple for us to go on a Wednesday.
Saw many acts there some long since forgotten!
Also paid to see some of the named stars, i.e Three Degrees, Tommy Cooper, Chilites, Drifters, Mud and the fantastic mr cool Jene Pitney etc.
One of the best acts to stick in my mind was a group called Limmie and the Family Cookin, sung You can do Magic, Smarty Pants .......
They were brilliant, remember the lead singer crying with emotion due to the audience reaction.
Unfortunately due to stars wanting so much money these days by only playing big venues, places like this will no longer be.
