They were the most successful American pop group of the 1960s—
a group whose 12 #1 hits in the first full decade of the rock and roll
era places them behind only Elvis and the Beatles in terms of chart dominance. They helped define the very sound of the 60s, but like
fellow icons the Beatles and Simon and Garfunkel, they came apart
in the first year of the 70s. The curtain closed for good on Diana
Ross and the Supremes on January 14, 1970, at the Frontier Hotel
in Las Vegas, Nevada.
