Andrew Gosling, who has died aged 71, was a television pioneer. In 1974, he was one of the first to use blue screen, a by-product of colour television, while he was directing (and I was producing) the musical comedy series The End of the Pier Show for BBC2.
The show featured John Wells, John Fortune, Madeline Smith and the composer and conductor Carl Davis, with three new songs and a couple of guests each week. Wells once described it as “a programme for dirty-minded insomniacs”. Andrew had heard that if a particular colour were isolated, he could make our microscopic studio look bigger by inlaying artwork behind (and sometimes in front) of the performers, and give perspective by “drawing” the scenery. The illustrator Bob Gale agreed to create dozens of artwork captions for each programme.
