Just a correction to my OP, part of which was removed. I've extracted the relevant segment from the original video, so it's hopefully kosher now.

New link: https://www.youtube.com/watch?v=4arKbXbi7Fk&feature=youtu.be

The segment is from some music video that I'm now trying to find, but I don't recognize the song.
The molasses/pies scene appears to be incomplete (heavily edited) so finding the original music clip would be so much better.

Does anyone know where it is from, or what is the original music video/song?

Pinhead, thanks!
