I wonder if anyone saw the Grey's Anatomy episode where the cast sang almost the entire episode?

Someone reminded me of it today and I remember turning it on and thinking it was very strange. Lots of people apparently loved it but not me. It was like a bolt of lighning out of the blue. It's not that I didn't love the songs from the series but to see the cast singing them as they went about their daily work and tragedy was quite odd to me.
