Two incredible dance videos

I don't know where the first one was done. The second is from SYTYCD and is known as the "Breast Cancer Dance"

ETA: I put this in the Dog House because of the subject matter of the first video. It is done very cleanly with great technique - nothing "dirty" - but I sensed it should go here.

Wow, that first video is amazing!

The second one with Melissa and Ade, I've seen the dance before (because I watch SYTYCD). But what's strange is on the original show they danced it to Kelly Clarkson's song, Already Gone. Which in my opinion was a more powerful song. But it is still a wonderful dance.
