The music world suffered a blow Sept. 29 when trailblazing singer Helen Reddy passed away, at the age of 78. The Australian singer emigrated to the U.S. in the 1960s to make it as a solo star, and did just that by landing a trio of No. 1 hits on the Billboard Hot 100 and a total of 20 titles on the chart.
Among them, the 1972 feminist anthem "I Am Woman," which was the first Hot 100 leader by an Australian-born artist and the first Australian-penned song to win a Grammy Award.
