I once found this through Cartoon Network's old UK site (from 2009). You can access it on Wayback but unfortunately you cannot access the video. Because it's not on the site NOW and the fact that if you use Wayback, RealPlayer would not be supported on the old version of the UK site. However, years ago (when I was 8/9 years old), I did place it on a mix-CD with a bunch of other cartoon songs (despite this not really being in the series itself, and more as a "special feature") so I decided to upload it. Unfortunately I cannot show footage because A: copyright and B: (the main reason) because I can't really get it, unless someone told me.
