So there we were, a couple of hundred musicians, artists, writers, photographers and old blues and R&B fans crowded onto a Bournemouth town centre pavement outside an unremarkable row of shops, bars and restaurants. Those in the know were staring nostalgically at a nondescript door sandwiched between an Italian coffee shop and a Polish Delicatessen. For beyond that door, at number 9 Holdenhurst Road, lies a flight of stairs leading down to a dingy cellar where, 53 years ago on 3rd May, 1961, the town’s first full-time jazz, rock and blues club was born.
