Channel 4 is making some of its classic comedy shows available on its catch-up service All 4 to mark World Alzheimer’s Day.

Watching films and TV shows from the past can benefit people with Alzheimer’s by acting as a memory aid, so Channel 4 will also be broadcasting its original 1982 Lambie-Nairn idents on Saturday 21st September as well as releasing ‘Old Favourites’.
