I must know the song at the beginning of a certain video...

I’m not a huge fan of this Phil Vassar guy, but I was off to his concert and I decided to watch a few videos first, you know, to check things out. I found this video, and there’s a sample of a song at the very beginning. I remember it distinctly from a long time ago. It’s been bothering me not knowing what that song is – can you help me please? Thanks!
