The Grammy winning Isley Brothers (Rudolph, Ronald and O'Kelly Isley) wrote and recorded the single "Who's That Lady" for the first time in 1964.

Some of the lyrics were changed, the song re-written by the six members and the song was re-introduced as "That Lady (Parts 1 and 2)" (lead vocalist Ronald, O'Kelly, Rudolph, Ernie, and Marvin Isley with brother-in-law Chris Jasper) by The Isley Brothers in 1973 for the platinum album "3 + 3". This is Part 1 that peaked at number two R&B and number six on the Billboard pop charts.
