For those with digital telly and access to ITV4+1 then tune in at 1945 to catch on old World of Sport clip. It's just finished on the normal ITV4 channel.
It features a fantastic race of old DMS LT buses on a racing circuit at Ipswich in 1980. The bus were all supplied by Ensignbus as there are paper signs on the front. It's quite possibly the most ridiculous "race" I've ever seen on the telly.
