History:

Adapted from a recipe in Vincent Sardi Jr. & George Shea's 1988 Sardi's Bar Guide.
As for the origins of this cocktail, David Wondrich says "in 1972, the O.J.-and-Bacardi version starts appearing in the Chicago suburbs, whence it spreads to the rest of the Midwest, California, and eventually Sardi's, right there on little old West 44 Street. Back in Greater Chicago, it apparently began as a golf course and country club drink, but beyond that its origin was unknown.

RUM STONE SOUR
