Just reminiscing - in the 70s/80s a December night with the family round the telly was guaranteed to be interrupted at least once by carol singers at the door.
These ranged from very professional charity groups doing fully harmonised performances to a couple of dodgy-looking teenagers mumbling 'We Wish You A Merry Christmas'. They'd go away amicably enough if you gave them 10p.
I haven't seen carol singers now for at least 30 years - what happened to them? Are there any still in your area? Are you or have you ever been a carol singer?
