Hi
Just came across this site by chance, but I was the Senior Cameraman on the first four series of Wizadora and also composed the theme tune. If anyone's deperate for a copy (!) I've still got a cassette copy of all the original incidental and theme music (opening and closing).
Just for info, the programme was shot at the now-defunct Fountain Studios at New Malden and the music was recorded at a studio in Ashford, Kent, near to where I live.
Hope that's of interest
