There's a song playing in the background while the man is speaking.
What is this song? link.
(BTW, I've tried reaching to him through facebook, but he didn't answer).

That's the Manhattan's classic "Kiss and Say Goodbye." I was able to catch a bit of the lyrics, and it's a song I know fairly well so I recognized it. If that video is the last in a series, it may have been chosen deliberately for its message.
