I stand corrected.

Taken from www.allmusic.com:

Three bands were the undisputed arena rock kings of the early '80s -- Styx, Journey, and REO Speedwagon -- yet all weren't overnight success stories (in fact, each group began pursuing different musical styles originally -- prog rock, fusion, and straight-ahead hard rock, respectively, before transforming slowly into chart-topping mainstream rockers). REO Speedwagon first formed in 1968, via a pair of University of Illinois students, keyboardist Neal Doughty and drummer Alan Gratzer. After graduation, the group signed on with then-unknown manager Irving Azoff (who would later guide the careers of such multi-platinum acts as the Eagles and Steely Dan), which led to the outfit building a devoted following in the Midwest due to nonstop touring. By the early '70s, Doughty and Gratzer had welcomed aboard guitarist Gary Richrath, who would soon prove to be the group's spark plug (and one of rock's more underrated players), in addition to bassist Gregg Philbin and singer Terry Luttrell. It was this lineup to be featured on the quintet's 1971 self-titled debut recording for Epic Records.
