This isn't folk either. I saw the Led Zeppelin Unledded MTV show on very late night TV probably back in 1994 and should have gone to sleep because I had to go to work the next morning but I couldn't stop watching it.

I was very surprised and pleased to see a hurdy gurdy in this clip:

Nobody's Fault But Mine

I'm guessing that the hurdy gurdy player was Nigel Eaton.

I do like a hurdy gurdy when it is played well. It can be a real crossover/fusion instrument.
