Iam Tongi

The 18-year-old's debut performance of James Blunt's 'Monsters' brought tears to the eyes of celebrity judges Lionel Richie and Katy Perry, and is the most viewed American Idol video on YouTube

In the final, Tongi performed the song again - this time as a duet with Blunt, tearing up as it ended.

"I'm singing next to a guy who has the most beautiful voice and he wears his heart on his sleeve and I felt just very lucky to be up there with him," Blunt said after the show.

Tongi was one of ten finalists vying for the last stage of the competition yesterday.

American Idol Judges praised Tongi who has garnered widespread support since making his debut on the show three months ago.

Tongi impressed with his sweet and technically-terrific performances of “Lava,” from the Pixar short, and followed up with a touching version of “Father and Son” by Cat Stevens/Yusuf Islam, a number that Tongi seemed born to sing.
