First recorded by Fleetwood Mac (1972).
Hit version by Bob Welch, writer (US #8 1977).
From the wiki: “Bob Welch joined Fleetwood Mac in 1971, and the group first recorded the Welch-penned ‘Sentimental Lady’ for their 1972 album Bare Trees. The song became a hit when Welch re-recorded it for his 1977 solo album, French Kiss. Christine McVie and Lindsey Buckingham of Fleetwood Mac sang backup on Welch’s solo version. Many Fleetwood Mac aficionados cite the Fleetwood Mac’s original version as the first song to explicitly reference the softer, more commercial West Coast sound that the group would later make their own.
“Donald Brackett, in his 2007 band biography, Fleetwood Mac, 40 Years of Creative Chaos, says of Welch’s song-writing: ‘Welch had the unique ability to encapsulate in a single song the travails of personal intimacy as well as the larger social picture in which we all lived.'”
