Some carols have been on the edge of extinction for a long time already. Peter Kennedy recorded a version of the carol "Down in Yon Forest" from a singer in Derbyshire in the early 1950's. Is this still being sung traditionally in Derbyshire today? And what of "On Christmas Day" and "The Leaves of Life", both collected from the Shropshire gypsy May Bradley in the 1960's? Do any other traditional singers still know them?
