WARNING: This will (probably) give you chills.

Finally, a video from a subway train that doesn't  involve someone who's heavily intoxicated getting in a big fight or screaming match.

We need more subway trains like this!

This happened on the Long island Railroad and the footage has since gone crazy viral. See, everyone loves a good feel-good video!

In the footage, someone asks a Billy Joel impersonator to sing a few bars. He, of course, obliges, but no one knew what was about to happen next.

After the impersonator kicked it off, the rest of the passengers couldn't help themselves, they just had to get in on that "Piano Man" action.

You have to see this!
