My parents were among the last generation to like Frank Sinatra, the last really big pre-rock musician, while not being too impressed by the Beatles, one of the first really big rock bands (I count Elvis Presley as a transitional figure, a proto-rock musician). Thus, I associate Sinatra and the Rat Pack with traditional side of the 1960s social and cultural revolution in the United States. But, before the sex, drug and rock and roll revolution of the 1960s, the nation was already neck deep in the civil rights movement that sought to end racial segregation, which really took off in the 1950s. My parents, who were first generation college graduates and urban professionals who grew up in the rural Midwest, were a part of this movement themselves, particularly during their days in Atlanta, Georgia in the 1970s.
As a Square State diarist "fake consultant" explains, it turns out that Frank Sinatra was an important celebrity supporter of the civil rights movement who used his popularity to pressure Las Vegas venues to integrate and spoke out in favor of integration of the person to person friendship level. Who knew? It certainly gives me more respect for this music legend to know that this was the case.
