Tapdancing topless would be very ouchie I'm sure...
A friend of mine is actually a tapdancer by profession, she teaches it at schools and performs - every year she/her group takes part in the Parade festival, for example, which takes place in the four main cities every year - for that piece alone they start preparing well, about now, or earlier already ...
I couldnt see her performance last year of course but I saw it the year before, very modern / agressive - about as far from Fred and Ginger as you could imagine ... like a real musical instrument.
Interesting - but no, ouch, not something to do topless!
Its funny, she studied to be a social geographer, focus on georgraphic information systems, was good too - but she developed RSI, so had to stop working with computers - and now, nine years later, she's a dancer!
So you never know, Dag... ;-)
