I was hoping to find the clever Noeline Brown performing the shop keeper skit but it predates the Internets by many decades.
What I did find was the Son of the Naked Vicar show and track 7 is Shop! (At the 13:13 mark) Noeline and Kev.
Also on the file.
Track 1 Mack one of the earliest anti homophobes clips.
Track 2 Cricket. Back in those days you could hang shit on Richie Benaud but eventually he became untouchable in these fragile and sensitive times. (I prefer the old style)
