Air Supply's dynamic duo of Russell Hitchcock and Graham Russell wows the city with their classic power ballads and entertaining stage antics. Rebecca Lo sings along with the sold out AsiaWorld-Expo crowd.

We all have guilty pleasures. For some, it's chocolate; for others, it's reality TV. For me, it's Air Supply.

The chart-topping love ballads by Australians Graham Russell and Russell Hitchcock may be more familiar as Muzak to younger audiences. But no one can deny their influence on soft rock's development during its formative years. And everyone can hum at least one Air Supply song - or sing along to the choruses of their greatest hits.

"Yeah, no one will admit to being an Air Supply fan," chuckles Scott Murphy, my former colleague tasked with filming footage for Air Supply's upcoming DVD, which will be available by end of the year.

Yet a loyal gathering of 2,800 people begged to differ. Proudly singing along at the top of their lungs, they packed the soldout concert at AsiaWorld-Expo - and reaffirmed that the 60-something-year-olds still have what it takes to make stadiums rock.

"We have many friends here," said Hitchcock in the green room prior to the one night only show presented by Midas Promotions. "We first came here in 1981 and there is always something different every time we come back."

"We'll be performing two new songs tonight," added Russell. "One of them is a dance song called Desert Sea Skies."
