At something of a crossroads in their careers, the future seemed a little uncertain for the group, but Atlantic Records connected them with producers Nile Rodgers and Bernard Edwards of the band Chic, and the situation changed. After some initial challenges to working collaboratively, the breakthrough album "We Are Family" was recorded and released by Cotillion on January 22, 1979. The lead single "He’s the Greatest Dancer" charted at number one R&B and was a number-nine crossover hit. In 1979, the record's anthemic title track "We Are Family" followed and became a worldwide smash charting at number two pop and number one R&B. The song and group were nominated for a Grammy Award and "We Are Family" was adopted as the official anthem for the Pittsburgh Pirates, who went on to win the World Series that year. Sister Sledge was duly invited to perform the national anthem at the opening game in front of 45,000 fans.
