Help with song

I was wonering if anyone could help me with a song. Not sure what the title is, only heard it once, and the only discernable lyric I was able to get was "Walking Down a Highway" (Its not Graham Coxon, I know that much). I heard it on a Showtime (the TV Chanel) Commercial. Sounded like Jack Johnson or John Mayer or something along those lines. Any help would be appriciated.

lol I think you need to give us a LITTLE more than that. I mean I am the name that tune CHAMP and my only special ability is knowing exact chords and every single word in the lyrics of literally thousands of songs on every genre (and if it sounds like I'm bragging, that's because it's the ONLY thing I'm good at. I suck at everything else. So if you're extremely good at making money, screw off if I sound cocky)
But I couldn't ID a song by half a written line. Remember anything else? Like maybe what a line SOUNDED like? discernable words that might have stood out?

I'll watch for the commercial again...

yeah me too
