Rodney Jerkins wrote this with the songwriting brothers Theron and Timothy Thomas, who go by the name of Rock City. The song samples the main riff of The Yardbirds 1966 track "He's Always There," which was originally on their Roger the Engineer
album. Because of the sample, that song's writers - Jim McCarty
and Paul Samwell-Smith - also receive writing credits on "When I Grow Up."
