Clipped from the New Album bonus DVD. You might be able to buy it at amazon.co.uk or some other online retailer. Shop around!
The New Album uses the original US audio. What luck!
Note: Viacom and Nickelodeon do not own the LazyTown license in the UK (they probably do for the Nick channel); however, they may own the audio from the US DVD. I do not own any part of this video or audio.
