In Central ITV we got the Kerry Vincent episodes in Feb 1988 and at that same time I remember watching her on a BBC2 drama called Campaign.

A quick browse through IMDB would answer this question, but that isnt as much fun as discussing it, is it? ;)

I do recall something about Lizzie Birdsworth / Sheila Florence being in Mad Max, and I do remember seeing a number of Prisoner faces crop up in some kids' programme my little sister used to watch - Round The Twist, I think it was called - there was Eddie the electrician and Po Face Powell as regular characters

BUT, I think my most amusing ex-Prisoner spot was seeing Bea Smith / Val Lehman on the Antiques Roadshow getting something valued.

I take it that this is from the Aussie version?

*EDIT*: Scratch that last remark, as I've just found it.
