Rod Stewart "This Old Heart of Mine (Is Weak for You) (Single & Video)"

"This Old Heart of Mine (Is Weak for You)" is a song by The Isley Brothers from 1966 that was a hit for them during their brief tenure on Motown's Tamla label. Featuring Ronald Isley on lead vocal, "This Old Heart of Mine" peaked at number twelve on the Billboard Hot 100, and at number six on the Billboard R&B Singles chart.

In 1975, Rod Stewart released a remake of this song that charted in several markets (U.S. #83). In 1989, Stewart released another version--this time a duet of the song with Ronald Isley that reached number 10 on the US Billboard Hot 100 chart and spent five weeks at #1 on the US adult contemporary chart. The later version was produced by Bernard Edwards and Trevor Horn and was released on Warner Records.
