I just watched an episode of AYBS? in which the staff of Grace Brothers were celebrating Young Mr. Grace's birthday. They traced his family to Wales and sang a mining song. Then they found out that his family moved to Wales from Scotland, so they did some Scottish dancing. Finally, Rumbold got a telegram tracing the family back even further. They all came out dressed in white smocks, floppy hats, and they all wore beards. They sang 'Up From Somerset'.
What was that last bit all about?
