Gravatt took his replacement in the studio sessions badly and quit the band at the end of recording, moving to Minneapolis to join the band Natural Life. Many years later, Zawinul paid tribute to Gravatt's skills and stated that he had been the finest of the band's "pure jazz" drummers as well as being "from the jazz side... my favorite of them all". With Gravatt gone and Dwellingham unavailable for touring, former Sly & the Family Stone drummer Greg Errico played on the "Sweetnighter" tour, but did not stay with the band afterwards.
