He wants to know the ins and outs of the cat's backside was the one I used to hear in the Mancheter area.

Do they have a preoccupation with arse's in Derbyshire? The Peak cavern in Castleton is know locally as 'The Devil's Arse'. The only other saying from that area I am aware of is 'better to live in Hope than die in Castleton' :-)
