I was going to say "How did I get into this??" but you're right — from 15:43 onwards there's footage of us at the Union Crew Weekend in Penzance last February. We're singing "Para Hern" ("Curing Pilchards"), which is based on a poem written by John Boson in the Late Cornish period, early 1700s. The duo earlier in the video, Salt and Sky, seem to be singing a different setting of the same poem. It was written in Newlyn and name-drops Karrek Loos y'n Koos — St Michael's Mount — so it's a good one for the local area!
