Jelly piece

Well what exactly is a jelly or a jeely piece?  A slice of bread and jam and unfortunately the tea i.e. supper of many kids in Scotland because there was nothing else at home for them to eat.  My mum used to come home from work telling us just how lucky we were.

and while we are at it, I've pasted a nice little song on here...which explains quite a lot of "typical" Scottish expressions too....
