It's no secret that a lot of Filipinos were impressed with Noven Belleza's medley of Air Supply hits he performed during the grand finals of "Tawag ng Tanghalan." It did win him the singing contest, after all.

But now, you can also count Graham Russell, one-half of the soft rock duo from Australia, among those who found the farmer's version of their hits like "Now And Forever" and "The One That You Love" amazing.

The singer-songwriter congratulated the Negros Occidental native for his win through an e-mail sent to local concert organizer Danee Samonte, one of the producers of the recent Air Supply concert in the Philippines.

"I just saw the singing contest on YouTube and the guy that won. He was spectacular. Please pass on my congratulations to him if you would!" Graham wrote.

Belleza won "Tawag ng Tanghalan" on Saturday, earning a near-perfect combined judges' score and text votes (99.96 percent), defeating other favorites Sam Mangubat and Froilan Canlas.
