Thanks. Yes, they were part of United Biscuits when I wrote to them three years ago. To be fair, their letter seemed genuine enough and surely if they didn't intend to make these biscuits again they could've simply said they don't currently have plans to produce Gypsy Creams.
What amazes me is that Gypsy Creams were very popular. Even in recent years I've heard them mentioned in numerous TV soaps and shows (although not by brand name, obviously). Even the late Richard Whiteley always use to mention them on Countdown.
I was reading somewhere that Mars are planning to relaunch their "Snickers" bar under its original name of "Marathon". I'm not sure why but I think it has something to do with a nostalgia-related promotion. So now might be a good time for me to write to United Biscuits again (who knows, they might decide to follow suit)... Surely I can't be the only one who misses Gypsy Creams?
