Conan is huge! I know people say T&S are short but I'm about their height and I feel like its not that short for a woman. That dude is tall.

Great song but they are always horrible live when doing this song. Are they just studio singers I wonder.

[@jakeoby9137]

Yeah you can tell they sing some parts of the song in a different way from the studio version, I still thought it was a great performance though

[@PRATERVXEX]

I don’t think this is bad personally, but in terms of whether they’re “just studio singers”, I can confirm they’re amazing live.

[@heatherlovesteganandsara]

I've heard them perform live, and they're absolutely amazing. I think this song just doesn't translate well to a live version

[@jtsnowman66]

I agree, the voices always sound weak and pitchy… the original is strong and more dynamic. Tough song to do live maybe… it happens.

They could do without the choir and where the fuck are their guitars?
