I know several 'Catters are interested in these, not only those of us who come from the Venice of the Midlands ( why don't Italians call Venice the Birmingham of Italy?).
While at the Skiffle Madness session I picked up a flyer from skifflers DPN+1 for a CD of theirs called The Unknown Boatman. (£6.50 inc P&P from Dave Illingworth tel: 0208 540 2919 for details .) Looks interesting.
