is there any way to find a band that play'd here inbetween 1956 and 1958

Check out the walls, lots of clues in that place. What was the bands name ? Good luck !

When I worked there in 1968 thru 1974 , Dean Armstrong used to play there....He had been there long before I started working...but I don't know if he was there during the time frame you are asking about.

I'm guessing no
