Wam,
I totally agree with you and said as much at the start of this thread about a list of well known celebrities from Brum never mind those restricted to Sparkbrook. It's proving to be as thin as expected. It's only when you stretch the boundaries to include the midlands that you get a better selection but again most are from a distant time. When I was a teenager Led Zeppelin practiced in West Bromwich. Other heavy rock groups also had a footing in the Black Country. Slade were big for a time and had their mansions on the Hardtop estate of Sutton Coldfield. Next to Justin Haywood of Moodies fame.
Steve Winwood is still on the scene but the whole pop scene climate has changed now with small venues a thing of the past. The mega productions still come to the NEC where Health and Safety are able to cope with the crowds safely. When I saw the Who at 'Mothers' in Erdington it was above a furniture shop. We were packed in like sardines and had to face the stage directly otherwise the volume would deafen/kill you if you turned side on. Half way through their set there was a break where everyone spilled out into the night to get some fresh air before cramming back for the ear splitting crescendo. The following morning I had blood on my pillow those were the days eh, eh, you'll have to speak up, eh you what pardon.
