Lady Gaga goes back to her roots, debuts new song at tiny London club

The newest song from Lady Gaga dropped yesterday, accompanied by a social media blitz that may or may not include this very raw video of her performing the song at a tiny nightclub stage.

We don't get to see much of the audience, but based on a number of Twitter and Instagram posts it appears that the performance occurred at the Moth Club in London. Despite the small stage, the energy and tightness of her performance is worthy of any of her arena or stadium appearances.
According to fans, this is the first recorded performance of the song. After Gaga's done with the tune she sits down in front of a keyboard, but it's not clear if she kept going or if the clip was just a carefully staged bit of "reality" for the song's release.
Either way, if you are one of the enlightened people who think Lady Gaga is the truth, here's yet another dose of proof for the non-believers.
