Well it looks like I've killed the thread stone dead so some clues. The answer to PatW's last picture in this thread and a Level 42 record from '87 reached no6 ? in the charts.
To be honest I know bugger all about level 42 but I was aware Doug lampkins dad rode trials. Give me a minute..
Neither did I but I remembered that song but I know a fair bit about trials riding from that era as I used to compete in trials around that era.
