Not everybody who packed baseball stadiums in the Seventies hated disco. Sister Sledge's "We Are Family" was the rallying cry for the 1979 World Champion Pittsburgh Pirates. "We won, we lived, and we enjoyed as one," said series MVP Willie "Pops" Stargell, who hit .400 with three dingers against the Orioles. "We were products of different races, were raised in different income brackets, but in the clubhouse and on the field we were one." During the epic seven-game series, Pittsburgh radio played the song endlessly, and Sister Sledge soon had themselves a Number One R&B hit and a Number Two pop hit . . . despite somewhat less airplay in Baltimore.
