Noreeen - What's the point! All the following comments would become meaningless! Anyway - I have made bigger mistakes than that in the past - why let a > or two worry me?
My assumption of origin is based on there being a Dance Team named Tatterfoals, although thinking back - they could be based around Scunthorpe, which would make it Lincolnshire, not Yorkshire. I think Banjoflower is or was one of their musicians.

A friend who came originally from Scunthorpe swears blind that the once tried to re-name the local technical college South Humberside Institute of Technology, with a logo containing the obvious Initial letters, until a new temporary secretary looked at the new letterhead and asked if they were taking the piss!
My assumptions on origin may be totally unfounded, but it's not an unreasonable guess!
Quack!!!!
