Hate to break it to you guys, but the likelihood that this song will ever be "released" is pretty much nil.
The spot is a year old and if the DDB and Clorox didn't see fit to pay for internet usage on the music, my guess is (and this guess is *very* educated since I have made about 200 ads for blue-chip clients) that they won't do it now.
Additionally, the probability is that, since it appears Rob Crow was hired as a session singer, Clorox actually owns the composition of the track -- not Rob. If Rob were to attempt to re-record it, he would be up for a lawsuit because Clorox most likely owns the copyright.
In any case, Clorox would have to pay extra to put the track on the internet. Even though they own the track, they have to pay for the exhibitions of the performances (per SAG's commercials contract to which DDB is signatory). They can't just "put it up" without a whole lot of paperwork and money.
My advice -- get a copy of the spot and listen to it over and over. Or better, invest in Mr. Crow's catalog so that, at least, he gets some financial benefit (other than his residuals) and "word of mouth" publicity for this performance.
He's in an indie band, so no matter how much you like the track, he's still going to catch a little hassle from his peers for selling out.
