Re:Howard Johnson canned soda
I do remember Howard Johnson's soda from the 1960's, but can't give the exact years it was available in NYC. It was cheap and sold in some supermarkets as well as at beer and soda distributors; they were plentiful then. I would buy the cream soda. The cola tasted like shoe polish. I don't know who produced it. HoJo still had their huge commissary in Hollis back then. There were also a lot of independent bottlers such as Kirsch, Cornell, Cott, Hammer, Minck, Mission, Hoffman, Dr. Brown's, White Rock, and Mission who could have produced it.
It hasn't been available for decades. Will probably never be resurrected again, either.
