The writing credits on this one are a little confusing. According to the song's publisher (Bridgeport Music), which writes the royalty checks, Clinton and Philippe Wynne are the writers. The single and album list Clinton as the only writer though.
Junie Morrison, who is listed as a keyboard player on the album and as the arranger on the single, clearly had a big role in creating the song (he is listed as a co-writer on "One Nation Under A Groove
"). Morrison, who was a member of The Ohio Players before joining Funkadelic, told Red Bull Music Academy
: "I created 'Knee Deep' using a drum machine, Fender Rhodes, Steinway Grand, Mini-Moog for the lead and bass lines and a Gibson L6S for my jazzy guitar solo. Bootsy [Collins] added his drums at a later date. In fact, Bootsy was also the drummer on 'One Nation (Under A Groove).' Michael Hampton added his monumental guitar solo to the Knee Deep mix some time later, as well. Although Bernie Worrell is a phenomenal musician, contrary to popular belief, he did not perform on "(Not Just) Knee Deep."
Morrison added: "The track is of my conception. It originally began with the idea, groove and keyboard parts that I had created a few years prior to producing the track for Funkadelic, which later became '(Not Just) Knee Deep," as you now know it today."
