From my younger days I especially remember (in no particular order so a few years range here!):
Saturday morning pictures
Clackers (frequently at above event!)
Dolly Darlings
Malt extract (my sis got a tablespoon a day, I was considered less weedy & didn't, unless I whinged so much they gave me some to shut me up! lol)
The local disco (visited my sis a few months back & barely recognised the building, it seemed so small & well, seedy! lol)
Hotpants
Chloe & Anais Anais perfumes
'Smash' potato (& the irritatingly catchy adverts for it with those ruddy aliens!)
Bri-nylon bedding (my sis actually found our old bedding in a trunk, mine was poo brown with hideous circles & hers was electic blue with an equally vile pattern on, ugh, I still shudder at the thought of both the pattern & the feel of it!)
Playing 'ball on the wall' for hours on end
Donna Summer (RIP Donna! x)
Radio Caroline
Platforms
Teapots & tea-cosies (usually at least 3 of the latter per teapot) & tablecloths (again, at least 3, a felt one, a wool sort of thing & a posher one over the top at mealtimes)
Stodgy puddings on a regular basis, e.g. jam roly poly, spotted dick....suet, suet & more suet basically! lol
Listening to the 'top 30/40', religiously, every week, who does that nowadays?
Buying those crispy ends from the chip shop, in a bag, calorific value off the scale I imagine!
Coffee Matchmakers (why did they stop making those?)
Those little metal/enamel badges you could buy from the local shop/P.O. etc. quite cheaply, little Scottie dogs & things
Wade Whimsies
Getting those Lindt choccy bunnies/puppies/chicks etc. at Easter (sliding box of 5 or 6 choccies)
Christmas stockings which were opened in bed!
Blimey, that's quite a list actually! LOL
