Mike Roberts started to assemble a group of top-notch musicians to fill a couple of gigs he was offered. Clarence Walker, Paul Rickman, Jack Atkins, and Andrew Vincent joined Roberts and Our Father's Sons Unlimited was born. After Ronnie Taylor's single lost its steam, he retuned to Columbus and to the most promising offshoot of his former band. Renamed OFS Unlimited for the sake of brevity, they were able to expand onto the national scene with Taylor at the helm. They would hit the road for weeks at a time, a schedule that would steadily wear the unit down. Despite a lifespan of less than two years, the OFS Unlimited band were able to cut two impressive singles for the Prix label and one unreleased session included here. Their first single was issued as OFS Unlimited and includes the dazzling funk instrumental "Mystic" on the flipside of the Ronnie Taylor-led "Mr. Kidneys," a take on the tale of the dreaded backdoor man, Jody. Clem Price was so impressed with the band's maturity that he called on them to back Mitch Mitchell on his lone release for the label.
