Joining in with an enthusiastic pub chorus of Khe Sanh is a rite of passage, so there are expected to be scenes today as tickets for Cold Chisel’s Big Five-O tour go on general sale at noon. Since announcing the surprise tour last week, the iconic band have added another 6 shows to the tour and fans are clambering for the chance to see remaining members – Jimmy Barnes, Ian Moss, Don Walker and Phil Small – perform live for what could be the last time. The tour is set to kick off in October, starting in Armidale, NSW, where they were based in their early days. On ABC TV’s Australian Story on Monday night, Barnes marvelled at how much their songs have meant to people. “People come up to me and say, ‘I played your songs at my son’s 21st. I danced my first dance with my wife to your songs’.” And in case you’re wondering, our favourite track changes regularly – ATM it’s Forever Now. You’re welcome…
