I've never heard that one, Richard, but I was surprised to see it on sale last year as a new 12" LP at Fopp, just off Market Street, which I'm sure you know.
I don't think you've missed anything Bill. From 1957, it's a nice line-up - rhythm section of Horace Silver, Curly Russell and Blakey, but it seems uninspired. I have to go into Manchester for work next week (not been for about 2 years) so I'll have a look in Fopp and Vinyl Exchange.
Surprised to hear that you haven't been into Manchester for two years, Richard, as you name Manchester as your location. Which part of Greater Manchester do you live in? (I'm in Didsbury).
