I've been looking for this song for months; it's been in at least three commercials for the show "Greek" on ABC Family.

Some of the lyrics are:
So tell me
Well/will you and i
(We'll/will) go back home
Get back (on the ground?)

These lyrics are just what I've heard in the commercial, but there's talking over it so I'm not exactly sure of them.

If anyone knows the artist and/or song title, it would be a huge help. Thanks!
