TORONTO -- The moon was close to full last night as it shone brightly in the sky above the Molson Amphitheatre during an unusually crisp summer night.

But not even the lunar cycle could explain the behaviour of Aerosmith's Steven Tyler, whose pouty-and-potty mouth schtick hasn't aged well after 31 years as the poor man's Mick Jagger.

"That was like the birthing process, and I got it all over me," he said, after the band slowly made their way through the crowd -- flanked by dozens of aggressive security -- to play on a smaller stage close to the lawn seating.

Yuck.

Sure, Aerosmith has a few classic rock songs up their sleeve -- Dream On, Walk This Way and Sweet Emotion -- but they simply weren't enough to propel the two-hour evening forward.

Especially considering those tunes are all from the band's golden period in the mid-to-late '70s. They hardly made up for the abundance of new material -- from Aerosmith's latest album Just Push Play -- that concert-goers had to suffer through.

LIKE A ROCK STAR

Not that the audience seemed to mind. In my row, there appeared to be a lot more interest in getting beer than actually watching the band.

Tyler, meanwhile, was decked out like a rock star in a white leather jacket, a white T-shirt decorated with a dollar sign and pants whose design was comic-book art.

He even seemed to have borrowed some white plastic sunglasses and black sandals from daughter-actress Liv.

To his credit, Tyler was in good, strong voice but guitarist Joe Perry was certainly a more subtle presence of the two as he handled his lead duties in workmanlike fashion alongside Brad Whitford on guitar, Tom Hamilton on bass, Joey Kramer on drums and a touring keyboardist.

IMPRESSIVE LIGHTS

Playing on a gleaming silver stage with impressive lights and sound, there was also a platform in the shape of an oversized hand with long fingernails onto which Tyler would occasionally step. For what reason I'm not sure.

Among the singer's other activities were falling to the ground and humping the air, swinging out over the audience on a rope and pulling up his shirt to show us his nipples.

The phrase, "Me Jane. You Steven." comes to mind.
