At canal festivals one of the "joys" is working on the "Lavender Boat" which goes round each morning - ringing a big handbell and giving the traditional cry of "Bring out your dead". At one IWA National Gathering at Peterborough we gave a fantastic concert using the large effluent tank which was aboard nb Hesperus as a stage. Dave Blagrove, kept asking the audience "What do you think of it so far ?" and then pointing downwards !. The tank was well capped - thank god and anyway people who use porta-potties etc usually put plenty of "blue" in them.
