First recorded (as “Keep Growing Strong”) by Connie Stevens (1970).
Hit versions by The Stylistics (US #3/R&B #2/UK #13 1972), Prince (US #31/R&B #10/UK #11 1996).
From the wiki: “Thom Bell and Linda Creed wrote the song that was originally recorded by Connie Stevens as ‘Keep Growing Strong’ and released on the Bell Records label in 1970 with no chart impact. But, the composition scored a hit when it was covered by the Philadelphia soul group The Stylistics in 1972 peaking in the US Top 10 and UK Top 20. (Surprisingly, Bell produced both the Stevens’ and Stylistics’ recording sessions.)
“Another cover version was released by Prince on the 1996 album Emancipation on his NPG label. Prince has stated that he always wanted to release a cover version but his record company, Warner Bros. Records, had not permitted it.”
