I used to love parma violets, fruit gums, fruit salads, texan bars, spangles and those lollies that were like hard sherbet and 2 different colours. Other than those I didn't bother much with sweets, though I was rather partials to treacle toffee which, if I remember correctly, used to come in a big slab and was then broken up into weird shaped pieces.
I have occasionally seen fruit gums and parma violets around but no idea if any of the others are still available. I'll have to call in at our local vintage sweet shop for a bit of nostalgia.
