Why dont people understand? the set list generally is pretty much the same give or take maybe 5 songs. This is because they are the most well known songs. I am a massive fan and have been for about 15yrs, but i do understand that a high percentage of people attending now are not so die hard and many wouldnt even know unreleased singles and album tracks.
How can Bon Jovi play a gig and leave out Bad Medicine or Bad Name, these are songs the EVERYONE knows, its why most people go to see them.

Would like to see a GNR concert when they dont play Paradise City, Sweet Child O' Mine or Patience, of course not.

Now argue with that!!!!!!....
