In Britain (and perhaps elsewhere) there used to be a soft drink called 'Zing' which I was very fond of. This was in the late '60s and early '70s ('though I'm unsure of exactly when it started or finished), and it came in a variety of flavours. It seems to have disappeared in the '70s and I never saw it again - until, that is, the mid-'80s, when I saw it in the cafeteria of a motorway service station on my way down to London. It was served at the counter from a dispensing pump, not bottles as it had once been, but only in orange flavour. I'd love to know if it still exists.
I don't think I ever drank Wink, but back in the day, there was a Mom & Pop store down on our corner, which I mentioned here: http://1967topps.blogspot.com/2010/04/this-is-where-it-all-began.html...where, besides buying baseball cards and candy and popsicles, we would collect all the bottlecaps in the bin below the bottle-opener oon the side of the cooler. I can remember getting all kinds: Wink, Like, Tab, Hires, Booth's, Frank's, 7-Up, Yoo-Hoo, Coke caps with NY World's Fair scenes under the cork, etc, etc.
