I'll Be Good To You (Pt 1, 2) (With Chaka Khan, Quincy Jones) (1989)

I'll Be Good To You originally was a 1976 hit song by R&B duo The Brothers Johnson. The Brothers Johnson's producer Quincy Jones heard the song, liked it, and convinced George to sing lead on the finished track. Released from their debut album, Look Out For #1, it was a top-ten hit on the Billboard Hot Singles Charts, peaking at number three, and a number one song on the Billboard R&B Charts.
14 years later, it became a number one R&B hit again, with Chaka Khan and Ray Charles doing the vocals on Quincy Jones' Back On the Block album (the record also went to #18 on the Billboard Hot 100 Singles chart, and topped the American dance chart in early 1990). This was Ray Charles' first #1 R&B hit in twenty-four years.
