The band achieved peak popularity and success during the 1970s with hit songs such as “We’re an American Band”, “I’m Your Captain (Closer to Home)”, “Some Kind of Wonderful” (a cover of Soul Brothers Six), ” Walk Like a Man”, “The Loco-Motion” (a cover of Little Eva), “Bad Time” and “Inside Looking Out” (a cover of the Animals).  Grand Funk released six platinum and seven gold-certified albums between their recording debut in 1969 and their first disbandment in 1976.

Known for a crowd-pleasing arena rock style, the band toured extensively and played to packed arenas worldwide, and was well-regarded by audiences despite a relative lack of critical praise.
