Would it be inappropriate for them to bring the grandkids with them? There are concerts I would want to take my grandson to, to expose him to live music, esp. as long as it was an appropriate venue, i.e. children allowed.:-)

Unfortunately, a substantial portion of the present generation of children have been raised under the concept that not letting children express themselves when they wish is damaging to their self-esteem. Any crowd with a significant number of children in it will include a sufficient number who won't shut up and let others listen, to ruin the concert for everybody.
