My Dad had a great baritone voice but sang nothing but Gilbert and Sullivan. He used to play all the comedy parts in the local operatic society. I remember bringing home an LP (long time ago now) of Ella Fitzgerald and in the interests of good taste I can't possibly tell you what he said! There was never any folk music in our house so I don't know where I got the bug. Perhaps from my mother singing pseudo folk songs with the W.I.
