I filmed Dave talking about his discovery one year later, at the 1989 TA AGM on 1989 June 24 at Basingstoke. I’ve just uploaded the short clip to youtube. No smartphone videos then… A huge shoulder mounted camera and a heavy VHS recorder slung around my neck! Nick conducted the interview. You’ll find it here:

Seems like yesterday!
