I even have the Catweazle theme tune as a ring tone for a few people

Hard to believe that Catweazle only ran for two years.

Who still uses his words telling bone and elecktrickery?

Tony

Include me in that but I didn't realise whence they hailed.

Certainly Electrickery, telling bone could be confused with something else by those who did not watch the series.:D
