"I'll Be Good to You" is a 1976 hit song by R&B duo the Brothers Johnson.

While George was recording a demo for the song, family friend Senora Sam came by and added some lyrics.

[1] Brothers Johnson producer and mentor 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 during the summer of 1976.

Thirteen years later in 1989, it became a number one R&B hit again, with Chaka Khan and Ray Charles doing the lead vocals on Quincy Jones' Back on the Block album, and went to number eighteen on the Billboard Hot 100 Singles chart.
