Saturn Ion Commercial Song

Trying to figure out who the hell does that song in the Saturn Ion commercial. C’mon, you know, the one where the car full of young adults drives past house after house of kids playing on swings, slides, and those bouncy horse things.

The singer sounds very familiar but I just can’t place it.

We’ve Been Had by The Walkmen.

Don’t thank me, I learned that from a similar thread on SDMB about three weeks ago.
