The Sheffield carolling tradition is alive well and thriving

The most popular pub for carolling is the Royal at Dungworth, a country pub middle of nowhere. Carolling starts first Sunday lunch after Armistice day and singing in very many pubs around Sheffield and into Derbyshire. It is ai believe a Living Tradition and passed on initially by word of mouth and added to by choirs such as Bolsterstone, Penistone and the like and odd songs picked up and popularised by local singers (eg Will Noble)

Goes across into Sth Yorks and some songs I know sung in Barnsley and Cleckheaton and Huddersfield in W Yorks at Christmas

the folk clubs have done a great deal to continue the singing tradition too and Sheffield currently has a lot of younger singers Hield/Boden/Fagan/Kerr/Richard Jess Arrowsmith/Davenports/ and a pub scene for alcoholics to thrive. Fagan's, Grapes, Kelham island Irish others genres

O must not forget Dr (Prof) Ian Russell who has worked for years recording and fostering the Local Carols
