BBC2 TV for insomniacs clip - Thames Evadne Fisher in-vision 14th July 1993

This is quite a strange clip from a BBC2 programme called "TV for insomniacs" This clip features Thames announcer Evadne Fisher in-vision, this was broadcast on 14th July 1993, Thames in-vision had ended in early 1991 and Thames had lost it's ITV franchise on the 31st December 1992, so seams the BBC had this programme in the can for over 2 years.
