The band recorded with some regional success between 1966 and 1970, at first for Mercury and subsequently for a variety of record labels. Almost all of their singles charted on radio stations in and around Milwaukee, Wisconsin. As well, their 1966 single "Race With The Wind" was a substantial hit in Chicago, and several other singles were breakout successes in smaller markets such as Honolulu, Hawaii and Columbus, Ohio. An early single was co-written and produced by the team of P.F. Sloan and Steve Barri, who had earlier written a hit single for the (then) strictly studio-concocted band The Grass Roots. Sloan and Barri reportedly offered The Robbs a chance to step in and actually become The Grass Roots for both touring purposes and for future singles, but the group turned the offer down.
