years ago..maybe late 60's early 70's a chewing gum shaped like a Polo Mint..it was flesh colour if i remember rightly..and it whistled..when you would sit it between your lips and blow..
looking at what i wrote i hope no-one has their mind in the gutter..i don't know how else to explain it..
no i don't think it was cinnamon.. i don't think it actually had a flavour..
it just tasted like the yuckie cardboard kind you used to get with packs of cards years ago..you know the kind that tasted of paste and broke up into pieces after a couple of chews..
