Sax player in NYC subway plays Bruno Mars tune as homeless man dances

This sax player was doing his jazz rendition of Bruno Mars' 'That's What I Like' when a homeless man started dancing along.

In the video, the man can be seen grooving to the tune and even laying down some floor moves. Towards the end, the pair are joined by a few other passerbys, some dancing and others filming the spontaneous act on their phones.
