There was certainly an edition broadcast in the Midlands on 15 November 1977, which might have been the first. (The British Film Institute archive has it down as having started in the Midlands in "early 1978", which is definitely incorrect and I'll get in touch with them and see if I can get it changed.)
The one from 1964 definitely isn't the same programme as if you look at the entry, it's a radio programme! The equivalent programme in the 1960s was "Wheelbase", which ran for years and years but seems to have been completely wiped from the collective memory.
