Norman Gunston sings Liza with a Z

I found this on an old video tape, just as is - this song on its own. I suspect it was in one of his shows,but don't know if it was at the ABC or on Cannel 7 (Australia). I haven't seen it anywhere else on the net, so it may be totally new to most people. It scrubs up pretty well. Enjoy a great performance from one of Australia's funniest comedians.
