Hello Pete,
I played in the Bradbury Hall for a couple of weddings, that would have been around 1963-ish. The dance floor was horrendous, with knots in it like the Himalayas. I also lived almost directly across the road (with my parents) for probably five years or so in the mid-late '60's. Having not lived in Chesterfield for thirty years, and being a very infrequent visitor, I was totally gobsmacked to learn (just now) that it's not there anymore.
Thank you for the opportunities to look at the pics, Pete, it's a valuable job you do. On this occasion I might have preferred to remain in the dark, I suppose. Many thanks again.
