I'd like to see the return of blues to my local jazz club. Try contacting Miles@jagz.co.uk (Ascot, Berks) or Bob who runs Jazz'n'Stuff at South Hill Park, Bracknell (including Blues)http://www.jazznstuff.co.uk/
Pete Feenstra at: http://www.feenstra.co.uk/ books blues and blues-rock for a series of venues in Surrey like Farnham Maltings and the Ram Jam Club.
Best of luck
