REO Speedwagon is an American rock band that grew in popularity in the Midwestern United States during the 1970s and peaked in the early 1980s.
REO Speedwagon took its name from the REO Speed Wagon, a flatbed truck and fire engine, manufactured by the REO Motor Car Company. ("R.E.O." are initials of the company's founder, Ransom Eli Olds, who also founded Oldsmobile, once a division of General Motors.)
In 2000, REO teamed up with Styx for an appearance at Riverport Amphitheater in St. Louis.
