danny_boy seems to have a UK broadcast recording:

but he says his was broadcasted in '82, you might want to check with him 7FN.
Personally I would like to know if there has been any of these UK TV-broadcasts made available for download someplace, as the transfer they used for them are quite unique among the many pan & scan versions of the film, I would very much like to see one of them preserved.
