Well it was part of being young, and I look back with great fondness on all the really crap pies I've eaten.

Lyons Individual Fruit Pies - the fruit filling always tasted the same, whatever the supposed flavour - 100% sugar!

Walls Steak and Kidney in attactive cellophane packet with a blue and red badge. It was before microwaves - they used to be lodged for weeks in a little stove/display that sat on the pub counter. The filling was so hot - the taste was something approaching an oxo cube dropped in nitric acid. Each pie had at least one lump of gristle that you could have mended the sole of your tuf town shoes with.

Pukka Pies mentioned before. these were an exciting addition to 1960's cuisine - there were exotic flavours like Chicken and mushroom - with meat that was recognisably and unarguably chicken. Unfortunately the pastry - particularly of the base did bear an uncanny resemblance to thick damp cardboard.

In 1965, My Uncle George from Brecksville, Ohio came and paid us his one and only visit. Wherever he went - he kept requesting Pizza Pie. In Lincolnshire at the time - Pizza was completely unknown. So people just thought it was his exotic pronunciation and they kept bringing him a piece of pie.
He went home a disappointed man. It wasn't til years later, we got together as a family and fathomed out the source of his frustration.
