I remember it very well indeed - a really good film. The story was written by the novelist William Boyd and it was screened by Chanel 4 in 1983 (shown again in 1986)
Good and Bad at Games is a brilliant film and should have had repeated showing. However here at home friends and I are tearing our hair out trying to remember ifCream's 'I Feel Free' featured along with the closing credits. Did it?
