Sometimes when we touch - Pacquiao duet with Dan Hill in New York Presscon

Pacquiao performed the song at a press conference in Las Vegas ahead of his title fight against Juan Manuel Marquez.
The Phillipino boxer released a recording of Hill's song in the run-up to his world title fight against Shane Mosley in May.
"I saw Manny and heard Manny sing it on [Jimmy Kimmel Live] and I really loved the way he sang it," Hill said.
"I was immediately drawn to the honesty and the gentleness of his performance. It was like, 'whoa.'"
Pacquiao will defend his welterweight title on November 12 in Las Vegas in what will be his third fight against Marquez.
