Never been to Colbolt yet either. Had a quick Google maps & it looks like it’s in a back lane.Had to Google it, turns out folklore! The lubberkin is typically described as a large, hairy man with a tail who performs housework in exchange for a saucer of milk and a place in front of the fire
It's a decent little DIY venue (smaller than Cobolt - same sort of vibe), right next to Alphabetti Theatre - really surprised that Goat Girl didn't sell more tickets.
