1983 - Cue a van with some workers in it wondering what's for tea, with each of them offering an accompaniment to said faux steaks to the tune of Que Sera:
# Will it be chips or jacket spuds? Will it be salad or frozen peas? Will it be mushrooms? Fried onion rings? We'll have to wait and see... Hope it's chips it's chips, we hope it's chips it's chips...# etc as they drive off.
A great advert that is still stuck in my head!
