Mother

McNeil says that Mitchum suggested the Ramos gin fizz as a hangover cure to Frank Sinatra. Sinatra found it so effective that he started calling Mitchum "Mother" and even mailed him a card every Mother's Day. "The Ramos Gin Fizz was also said to be a fave of Doors frontman Jim Morrison," the author of the Mitchum biography concludes in a dazzling non sequitur. (A late postscript! I don't know what Mitchum bio McNeil is reading. In the one I have, by Lee Server, the author mentions the hangover cure using much of the same language, but in a generic way, omitting its identity as a Ramos gin fizz. Nor does he make the weird aside about Jim Morrison.) PPS: Mystery solved! "Click" here for more information - ha! I know you never will.
