Hate to tell you, but that is NOT it. That's an ad from a trailering company. NOT the one that they promised. They have none of the song. They said the USEF was putting it out. That is not the USEF putting that out.
It was up briefly (not positive if it was official from USEF) and then taken down. My guess is either Colbert is going to use it and wanted them to take it down for some sort of copyright reason, or the powers that be decided it didn't represent the sport well and decided not to put it up (I only saw a few seconds of it, was going to watch it later but then it was private).
I saw the official one when it was up, and it was reallllly lame. Like embarrassingly bad. Including Brian pronouncing Colbert like "Coal-BERT" as opposed to "Coal-bear" several times. And Rafalca freaking out from the foam fingers. That's probably why they pulled it. If they took the good parts and edited it well, it could have been saved, *maybe*, but the raw footage made me cringe.
PS. I don't know anyone besides Brian in America who says "Dress-aahhhggeee", and in the original clip he stressed that pronunciation several times as if it's how those in the know would say it. Bleh.
