Good thread.. anyway, Gauloises Pairs semi final, Sheffield, 15th September 1977.
Heat 1: Doug Wyer, Craig Pendlebury, Martin Ashby, Geoff Bouchard. So I think that's a full house.
The 7 teams were Sheffield, Swindon, Belle Vue, King's Lynn, Wolverhampton, Bristol and Exeter. The only ones not here now are Ivan Mauger and Alan Wilkinson, plus Tony Boyle who was one of the track reserves.
