I do believe you've missed the point of YTMND. If you just want to see what happened on the show...just watch the show. Hey, there's even this upstart site called Youtube where you can watch the whole clip in full motion. Maybe you belong over there.

Can't help you with the full song, but if you copy/paste http://content.ytmnd.com//54000/54661/sound.mp3 you should be able to grab the 30 seconds or so that I used here.
It's not as strange as Dokaka beatboxing Katamari On The Rocks, but no matter how much it makes sense in the game, IT'S STILL DOGS SINGING. That's why.
