Wait, what song is that?

Last fall, this dad and this son completed the viral cycle by making a video titled "When Mama Isn't Home," in which the dad jammed out on the trombone while the kid manned the oven-gong. When I say "completed the viral cycle," I mean "their video was seen millions of times and then they went on Ellen." Now, they're back with the one song they were constantly requested to cover: Darude's 'Sandstorm.'
