The Ohio Express is a musical recording unit, mainly active from 1967 through 1970, and 1973, the 1980s, and 2003-Present to this day.
Though marketed as a band, it would be more accurate to say that the name "Ohio Express" served as a brand name used by Jerry Kasenetz's and Jeffrey Katz's Super K Productions to release the music of a number of different musicians and acts. The best known songs of Ohio Express (including their best scoring single, "Yummy Yummy Yummy") were actually the work of an assemblage of studio musicians working out of New York, including singer/songwriter Joey Levine.
Several other "Ohio Express" hits were the work of other, unrelated musical groups, including The Rare Breed, and an early incarnation of 10cc. In addition, a completely separate touring version of Ohio Express appeared at all live dates, and recorded some of the band's album tracks.
