should gnr play more new songs at their shows?

[Freya]

It's not 1991 anymore.  They can't play new songs without damaging record sales, so obviously it's highly unlikely, and if they do play a new one consider yourself extremely lucky. 

The majority of people going to the shows (unlike us hardcore fans) want to hear the old tunes.  So that, and a pool of six new songs they take turns playing is hardly unreasonable.
