"Strumming my pain with his fingers... Singing my life with his words..."

Killing Me Softly with His Song is a song about the pleasure and embarrassment of being seen. The feeling that someone has reached into your deepest, most private feelings, and laid them bare: "I felt he'd found my letters, and read each one out loud". It's a song about a singer, and about what music can do. And it's a love song that feels at once happy and sad.

The song was a huge hit in two different generations. It won Grammy Awards for The Fugees in 1997 and for Roberta Flack in 1974. Ray Padgett, author of Cover Me: The Stories Behind the Greatest Cover Songs of All Time, unfolds the layers of the song's history as a famous cover of a famous cover. The musicologist Nate Sloan explores what the song does harmonically, oscillating between major and minor chords to create a sense of uncertainty and longing. And Lori Lieberman tells the story of the Don McLean concert that inspired her lyrics for the song, that she was the first to record as a young singer-songwriter in 1972.

It's a song that transports Tiff Murray back to the hot New York summer of 1996, when the Fugees version blared from every car radio and shopfront. For her it was the soundtrack to falling in love while far from home. It's also a love song for Julie Daley, but now with a sharp edge. Dr Robin Boylorn listened to the Fugees version as a self-conscious teenager and felt a flush of recognition; Ben heard it the Christmas he first came to the UK from South Africa, played by a busker early one morning in Covent Garden as the first snow he'd ever seen began to fall; and Perminder Khatkar has treasured the song since it played in the delivery room during the birth of her first child.
