It was all glass when I was a lad, and not many empties around either, as you could get a few old pennies deposit back for returning them to the shop! Corona was a well known name in Northwest England, and you got money back for their empty pop bottles. I used to like Tizer too, particularly when eating fish and chips, but I'm not sure it tastes the same these days.
Also, do you remember the yellow cellophane wrapping on Lucozade bottles? You only ever got given Lucozade when you were ill in those days, and my mum could always tell when I was getting better as she'd catch me looking at the room through a piece of yellow cellophane! Perhaps that's why I like to use a yellow filter when shooting black and white film!
