Do you mean the 'big' Crown & Cushion on the corner of Wellington Road, or the 'little' Crown & Cushion right opposite, on Birchfield Road?
Being dragged up in Perry Barr, it was the 'little' pub that was known as the 'old' Crown & Cushion.
In the 1960's the 'big' C&C used to have some good bands on, on Sunday nights if I recall. I know for sure I saw John Mayall's Bluesbreakers with Eric Clapton there (my life-long heroes) and I think I remember seeing The Alan Price Set (not sure about this - you know they say that if you can remember the Sixties, you weren't there...)
