I agree with you jaqui.c and others who believe that if you go to a gig expecting a certain style/genre, whatever, of music/dance/song,then that's what you should get ('specially if you've paid). I sometimes attend classical concerts and love traditional and contempory music but whilst i would'nt mind hearing a Fairport song during the interval of a Mahler or Beethovan Janacek evening (i'm weird that way) i think the sex pistols or a bit of 'rap' music would definately un-nerve me a bit and stretch my tolerance level a bit too much. If i attend a poetry evening, i expect to hear poetry.

I would'nt expect or want to attend a morris dance session only to find it taken over by ballroom dancers (no offence to B/D's intended).
