There were two highly anticipated songs the crowd wanted to hear. Of course, Deep Purple played Smoke on the Water, their best known song from classic 1972 album Machine Head, and you couldn't help but grin with delight as guitarist Steve Morse - original Purple axeman Ritchie Blackmore has long since left the band - casually launched into those distinctive opening chords.
And you couldn't help but shout along as singer Ian Gillan, who, at 67, can still hit the high notes and let rip with his guttural growl, sang, "Smoke on the water ... and fire in the sky".
But earlier, there was an equally rousing, all-in crowd sing-a-long when American soft, and sometimes heavy rockers, Journey played their 1981 hit Don't Stop Believin' - the song made famous most recently when it got the Glee treatment. It's one of those guilty pleasure songs, but as my mate (a part-time Journey fan) also pointed out, in a bid to give it even more cred, it was the song that played during the final scene of the Sopranos finale.
Such is the power of Journey, and serenades like the beautiful Who's Crying Now and Open Arms (where the band's latest singer, Filipino import Arnel Pineda stretched out his soaring and velvety voice), that there were outbreaks of man love among a group of three lads who had been singing along to every song and breaking into air-guitar solos. But while it's anthemic tunes that Journey do best, they also showed a tougher side on the (almost) prog-metal of Wheel In the Sky and the punky Keep On Runnin' with wailing and flailing drummer Deen Castronovo taking on lead vocals.
