Bobby Womack, the legendary soul singer whose career spanned seven decades, died on Friday, according to representatives at Womack’s label XL Recordings. He was 70 years old.

Womack was born to two musicians, and his career began at a very early age as part of the Womack Brothers, who later became the Valentinos after signing to Sam Cooke’s SAR Records in 1960. One of the Valentinos’ singles, “It’s All Over Now,” later became a hit for the Rolling Stones in 1964.

After Cooke’s death, the Valentinos disbanded and Womack became a session musician, playing guitar on Aretha Franklin’s Lady Soul. His first solo album, Fly Me To The Moon, came out in 1968, and it was followed by a series of other albums throughout the 1970s. Womack put his career on hold after the death of his brother Harry in 1974, but the success of his hit song “If You Think You’re Lonely Now” in 1981 gave his career new life. His last album, The Bravest Man In The Universe, was released in 2012.

The cause of Womack’s death has not been determined, but he had been suffering with various health problems over the years. Before his death, Womack was in the process of recording another album for XL with contributions from Stevie Wonder, Rod Stewart, and Snoop Dogg.
