Dunno Bob,When I worked as a petrol pump attendent, I found out the chap who did the body repairs liked folk music and played banjo - I got my first go on a banjo in the garage and ended up buying a banjo from him (well 2 - 1st was a 5 string 5 and the second was a bakalite harmony tenor)...
Who knows, without the "pumping gas", I may have only ever got to play guitar and never tried more exciting things in life...? Not really - I'd have ended up getting a banjo anyway and as it turned out, it was a few years from then that I really tried to learn tenor (melodeon and morris dancing came in-between) but at least it is an alternative view point...
