Along similar lines - though not a direct comparison. When I was around 19 (and already a folk, classical and rock fan) I didn't think I liked jazz. I had moved to Winchester from Hartlepool (the home of a superb and usually packed folk club with an eclectic booking policy) so initially I spent a lot of evenings alone until I made friends. One night I wandered into a pub where there was a jazz band playing. Thinking I'd have a quick pint then find somewhere else I sat down. The band started playing - a Beatles song, can't remember which, but with improvisations around the melody. 'Ah this isn't too bad I thought' I could understand what they were doing. They played a few more. I never looked back and as I am typing this I am listening to Jazz on 3 :-) Now I dare say I may have got into jazz at some point without that band as I was very open to new experiences but it would not have happened so quickly
