This site talks about the Sky Bar, which it mentions as being like a Seven-Up bar.
So does this one, although it implies that the Sky Bar and the Seven-Up bar are the same thing.
This site claims that Seven-Up bars no longer exist and suggests Sky Bars as an acceptable substitute.
This site erroneously claims that the Seven-Up bar was a product of the ‘80s.
Finally, from here, a gold mine of Seven-Up Bar knowledge. It’s from the City Pages in Minneapolis, and claims that Seven-Up bars were made in St. Paul, were discontinued in 1979 (ah, I was but ten and beginning to lose my fat-kid innocence and prepare for fat-man disillusionment), and even lists the ingredients!
It was, as Ray Broekel chronicles in The Great American Candy Bar Book (1982) and The Chocolate Chronicles (1985), a wild and woolly time in the world of candy, and anyone with a little money and a dream could take a swing at nougat immortality. Imagine a time when a trip to the local drugstore allowed the purchase of Minneapolis's own Cherry High Ball, or one of St. Paul's own Trudeau Candies, such as the fantastic-sounding Seven Up, a bar composed of seven small, candy-box-style chocolates welded together. Its original incarnation featured four types of caramel, a Brazil nut, coconut, and jelly; by the time it was phased out in 1979, dark chocolate covered segments of mint, nougat, butterscotch, fudge, coconut, buttercream, and caramel. Now I feel gypped: Why are we stuck with Hershey's, Hershey's Almond, and Chunky? Bah, humbug.
I’m not crazy! You’re the one that’s crazy!!!
