When I was younger, you used to hear a lot about the generation gap: young people and their parents were said to inhabit different cultural worlds, epitomised by a range of issues but most particularly by their taste in music.

Yesterday's rally in Melbourne in defence of live music is as good an occasion as any to proclaim the death of the generation gap. The crowd ranged from teenagers through to the oldest of the boomers, now in their 60s; they may not listen to the same bands, but they share the same musical sensibility and a determination to defend it. Rock has won this battle.
