Cheers Bob, I have considered selling DUF a couple of times but then get cold feet despite serious offers. The problem is I just have no spare time these days, I generally work for 2-3 weeks without a break then take a long "lunchbreak" with Squeak or my Dad, and both of them have health problems.
Cheers Al, the Drum Car has not been out for a few years and needs new batteries, but is still stored in my workshop waiting for the right time. meanwhile it has inspired several people "as I always said it would!) to mount a drum kit on, for example, a motorcycle side car (see You Tube), then one guy drums while the other drives. Yup, they go a lot faster than me, but I was FIRST! And still the only one to do the drumming AND driving myself! The real difference though, is that mine IS slow and electric, therefore it IS suitable for use in processions and festivals, in supermarkets and pubs, on roads, pavements and in parks, so it is a more useful way to entertain the crowds!
