I remember when years back someone did the Freebird thing to Fugazi and they gave the guy the finger, a free "bird" as it were, ha ha.
People have said there is a need to update the song to shout out at gigs, maybe Rico Suave?
And this talking is not a new phenomenon, years back I went to Cracker when "Eurotrash Girl" was big. We left 1/2 way through the set (got in free) because you could not hear the band over the conversations. I put the problem more to people whose concert experiences are mostly those at bars where the band was secondary and just there for background noise. They take that attitude to real concerts.
