That's one to the Mudcat research team - still a lot of catching up to do.

Those two years were part of the experimental period when the Bank Holiday was in the process of being moved from the first Monday in August. I believe the legislation was eventually enacted in 1973 but no doubt one of the research team can verify that - there's Brownie points on offer here.

I have more than enough books Derek - some of which I have not finished colouring yet. A book on a festival I have never had any desire to visit would hardly be top of my list. Now one on the National at Keele, Loughborough and Sutton Bonnington might just be of interest - the ball is back with you.

Incidentally I had the butterfly location from Bob Spray but people camped in odd places back then.
