Ben, Steve had a programme of his own on Radio luxumbourg. Had a t.v series called Plectrum as well as "Muses with Milligan." The list probably is larger than those but He hasn't told me. There are very extensive Biography's on google. If you type in Steve Benbow guitar then you will probably be as amazed as I was at the sheer amount of stuff on there.
Steve has told me he worked for Anglia T.V as well as doing "Guitar club", "Saturday skiffle club" and "Easy Beat." That is as well as doing the stuff for the beeb! And that is as extensive as my knowledge gets I am afraid!
   Any questions or any comments please feel free to send me a mail.
    Best wishes.
