Two 'lost' Morecambe & Wise programmes, discovered in Sierra Leone as 16mm black & white films, have now been restored to their original colour using
BBC BASIC for Windows! Here you can see the various stages in the
Colour Recovery process on a frame featuring Kenny Ball and his Jazzmen. Both programmes will be
broadcast on BBC2 on December 26th and should be available thereafter on iPlayer. The BBC BASIC program is just over 3,400 lines long and processes the material at about 1.5 frames per second on a reasonably fast PC.
