Premise: "Sentimental Lady" is a song written by Bob Welch. It was originally recorded for Fleetwood Mac's 1972 album "Bare Trees", but was re-recorded by Welch on his debut solo album, "French Kiss", in 1977. It is a romantic song, originally written for Welch's first wife. Welch recorded it again in 2003 for his album "His Fleetwood Mac Years & Beyond".
Hypothesis: Fleetwood Mac was the first band to record Sentimental Lady.
