Harmonica in Bigmouth, a sample?

[Dirty0900]

Oddly watching a video about sticking GoPro cameras in random places. The harmonica sounds very much like the harmonica in Bigmouth. So is it a recreated piece by LI/UW or just pure conincidence? Video can be found here:

Coincidence. Sounds similar, but then, there are only so many ways to play the harmonica.

I think the playing on Bigmouth is Karl's actual playing. He's credited on the liner notes (under a pseudonym), and we've seen recently he can play it live.

the more you hear harmonica, the more you realize it all sounds like the the old west. ive seen karl play it live, but it does seem like all harmonica playing is derived from the same few songs; two settings: Blues or Old West.
