First recorded (as “Who’s That Lady?”) by The Isley Brothers (1964).
Hit version by The Isley Brothers (US #6/R&B #2/UK #14 1973).
From the wiki: “‘That Lady’ was a 1973 R&B and Soul hit song for The Isley Brothers (‘Twist and Shout‘), originally performed by the group nearly a decade before in 1964 inspired by The Impressions. Jimi Hendrix toured as a guitarist with the Isley Brothers in 1964 (and the band also employed Elton John on piano for their 1964 UK tour) and Hendrix’s influence was demonstrated on the 1973 re-recording of ‘That Lady’ with Ernie Isley’s guitar playing.
“The original recording was produced with a Bossa Nova arrangement; a more straight-ahead Latin arrangement, inspired by Santana, was used when produced again in 1973.
“Fun fact: The Isley Brothers are the only act to hit the Billboard charts in six straight decades and the only act to hit the Billboard Top 40 in five consecutive decades.”
