Did you ever see the series "Dossa and Joe" Bill ?
Set in Sydney and filmed around 2002.
It seems to have been forgotten about compared to her other stuff, but some good laughs in it when you understood the characters fully.
I first saw Caroline at a Comedy Club in Chorlton-cum-Hardy, Manchester called "The Buzz". It must have been 1989'ish. She was playing a character called 'Mitzi Goldberg' who was a Jewish Country & Western singer in a band. It was original and funny but she didn't seem to develop this personage to any great extent ?
'Sister Mary Immaculate', (an Irish Nun), was her breakthrough and hilarious.
I hope new people continue to discover her, a one-off and brilliant with it.
