"I'll Be Good to You" is a 1976 hit song by R&B duo the Brothers Johnson. George Johnson, one of the two Johnson brothers in the band, wrote the song after deciding to commit to a relationship with one woman, instead of dating several at a time. While George was recording a demo for the song, family friend Senora Sam came by and added some lyrics. 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. The single was later certified gold by the RIAA.
