I'm not familiar with this convention at all but I stumbled on this clip and it's truly a delight. I'm a Lucifer fan, so I know Tom can definitely sing (he does on the show) but it was delightful to see Sasha, David and Reeve (I was a fan of both Grimm and Penny Dreadful). I don't know the other two--Supernatural, perhaps? In any case, this was sweet, and as someone else mentioned, there's something almost comforting about it. Hard to explain. But the world seems just slightly less shitty when I listen to it.
