Back to Sid's filmography: A film made in 1995 to celebrate the hundredth anniversary of Édouard Martel's first descent of Gaping Gill. It features a reconstruction of that descent in period costume, with Andy Jackson assuming the role of Martel, supported by members of the Bradford Pothole Club, and Ged Benn and Sid Perou pay a visit to the Whitsun Series. Mel Gascoyne features in an extract from an earlier of Sid's films.
