On March 15, 1973, Roberta Flack was at No.1 on the US singles chart with 'Killing Me Softly With His Song'. Flack first heard the song on an airline, when the Lori Lieberman original was featured on the in-flight audio program. The song was born from a poem Lieberman wrote after experiencing a strong reaction after seeing Don McLean perform the song ‘Empty Chairs’.
