Visit to London - blues venues ?

[snakehips]

Hi there !

Will be in London on Monday 29th September, staying overnight, for an all day course on the Tuesday (then going back home that night).

Will be dropping in to Denmark Street (of course !) and Luthier's Corner too, to see Dave and Celine.

Any blues music going on that night (monday 29th Sept) ?
Any good venues to check out ?
Blues Jam sessions ?
Perhaps mondays not a great night ?

Any other guitar shops to check out ?

Thanks in advance !
