The song is called "Two Weeks." The video is kinda weird, but I think you'll find little to criticize with the mellow music. I like it.
Update I: (My son just emailed to say he liked the song. Which is great. But I meant to use this video for one of the days I would be gone. Now I'm going to have to find something else or jiggle with the posting date of this one. I'll take the course of least resistance and jiggle the date. This is what I get for being so anal.)
