You'd think that after Slash left the stage at Fort Canning on Monday night, he'd be busy indulging in some good old backstage rock-and-roll debauchery. But after you've (presumably) done all the sex and drugs in the rock-and-roll circuit for almost three decades, surely the thrill is gone. So what does a living rock god like Slash get up to after a gig? He updates his Twitter account. 'F***, what's in the water in Singapore? They f***in' rock!' it read.

Dropping the f-bomb may well be the frizzy-haired guitarist's last remaining rocker trait as he reminded a roomful of journalists earlier in the afternoon at a press conference that when not on the road or working, he takes his sons to the video game arcade, just like any normal dad. That image is a far cry from the Slash long-time fans of Guns N' Roses (GN'R) remember when he was with the band. Back then, he was rarely photographed onstage without a cigarette dangling carelessly between his lips and a bottle of whisky within arm's reach.

For his first ever gig in Singapore, there was none of that - though from the curly mane, top hat, sunglasses, leather pants and well-worn wife-beater, there was no question who was rocking the stage. And judging from the capacity 7,000-strong crowd of mostly middle-aged metalheads, nobody bothered if Slash has gone soft.

Though he no longer tours under his former band's moniker, the iconic guitarist knows he's still very much entitled to revisiting GN'R's back catalogue as his bluesy riffs made up the backbone of the hard rock band's sound as much as singer Axl Rose's shrieking vocals. Those who came were duly rewarded as Slash dug deep into the GN'R songbook, playing stadium anthems from the band's seminal 1987 album, Appetite For Destruction.

Alter Bridge singer and current vocalist of this tour Myles Kennedy did note-perfect renditions of GN'R classics like Rocket Queen, Night Train and Civil War. His range was not limited to just imitating Rose; Kennedy also stood in for Scott Weiland as the band tackled a handful of Velvet Revolver (which Slash was part of) songs sprinkled throughout the 19-song set. The lean 40-year-old slithered like a seasoned rock star, working the stage and rousing the crowd gamely even though it was hard-rock karaoke night.

But the star was Slash and his trusty arsenal of Gibson Les Pauls. He barely spoke throughout the night, preferring instead to let his six-string do the talking. For GN'R fans, it was the stuff dreams are made of as air guitars were raised in unison when the opening strains and signature riffs of Sweet Child O' Mine and Paradise City rang out.

Keen to keep the spirit of rock alive, the veteran guitarist also unselfishly shared the bill with his 'friends' (as he refers to them on Twitter) - upcoming Aussie hard rockers Twenty Two Hundred and American prog-metal favourites Coheed and Cambria. Twenty Two Hundred showed plenty of promise with a bass-heavy and guitar-driven rock sound while Coheed and Cambria tried pumping the audience but their lengthy songs evidently alienated some as the beer queues got longer.

By the time Slash and his band took to the stage at half-past nine, the head-bangers were more than ready for the main event and Slash obliged with a hits-filled two-hour rock show (complete with the obligatory drum solo). At 45, it's hard to believe the clean-living family man shredding up there is the same one who survived near-death encounters with drugs and alcohol abuse during the heady decadence of the late '80s and early '90s LA metal scene. Maybe it's true rock and roll never dies.
