Jon simply introduces this as, “A classic Sheffield carol.” It’s the first of several tracks that are marked chorus on my planner and Jon introduces his cohorts as “Jess and Richard Arrowsmith plus Gavin Davenport from Crucible, Sam Sweeney and Fay Hield, with occasional, additional chorus vocals from Lucy Arrowsmith (aged 10 months.) These songs were recorded by Andy Bell at the Royal Hotel in Dungworth.” Those seeking a little more on this carol and what seems to be a well established tradition at the Royal might like to start here and here’s another link.
