That's a hard one to track down; there don't seem to be many videos of it out there. I think it's their Fiesta on Ice 2008 performance to Beethoven's Spring sonata.
The one with the raincoats? That's from the 2006 Skate Canada exhibition finale :) Here's a link ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GGOqfoz6reQ.html
