Nick I do recall playing in a redundant Dingo at Kinnergar in 1969..all was going well until some idiot pulled the red switch...vehicle filled up with foam very rapidly so we beat a quick exit...I should like to point out that this same chap opened up a container of the radio active isotopes when we where delivering same under armed guard to Mosgrave Park Wing of RVI in Belfast..so we where all irradiated...wife often tells me I glow in the dark...best regards malcolm in a snowbound north-northumberland
