@tsarstepan,
some of the first television tapings I went to were when the hamburgers took me to New York when I was 12 or 13 - What's My Line, The David Susskind Show ... I kept going to ones in my hometown and then Toronto and the city I went to university in.
I think my favourites have been through our equivalent of NPR - I've had the opportunity to be in the audience for musicians whose regular shows I couldn't get tickets to (or couldn't afford).
