Out of interest, Mike Canavan, formaly of this Parish (Manchester) wrote 'Knocker Upper Man' as well as many other classics of Lancashire times gone by. One of my favourite of his was about the public swimming baths

"Ee, the load of mucky kids that used to come each day
down to t'corporation baths that were in Harperhey
In my mind I see 'em now, clear as yesterday
Kids all shapes and sizes, always dirty"

Can't remember any songs or chants with knocking in but I'll ask Mrs G later. I fondly remember though that, now the nights are closing in, we are coming into 'knock a door run' season. Glad we never got caught:-)
