I saw Fielding do stand-up at my uni about a decade ago. It was similar to this - no direction, mostly surreal and, at that point, seemingly made up on the spot. Overall it was unfunny. I didn't watch the Mighty Boosh because of it but eventually liked it when I did, mainly because the surreal elements he injected added to the whole. He seems now to have gone back to his own thing which mirrors his stand-up and has returned to being terrible.
