Roots of Hardrock

Grand Funk Railroad is an American rock band formed in Flint, Michigan, in 1969 by Mark Farner, Don Brewer and Mel Schacher (bass). The band achieved peak popularity and success during the 1970s with hit songs such as "We're an American Band", "I'm Your Captain ", "Some Kind of Wonderful", "Walk Like a Man", "The Loco-Motion", "Bad Time" and "Shinin' On". Grand Funk released six platinum and seven gold-certified albums between their recording debut in 1969 and their first disbandment in 1976.

Free were an English rock band formed in London in 1968 by Paul Rodgers (vocals), Paul Kossoff (guitar), Andy Fraser and Simon Kirke. They are best known for their hit songs "All Right Now" and "Wishing Well". Although renowned for their live performances and non-stop touring, their music did not sell well until their third studio album, Fire and Water (1970), which featured the hit "All Right Now". The song helped secure them a performance at the 1970 Isle of Wight Festival, where they played to an audience of 600,000 people. In the early 1970s they became one of the best-selling British blues rock groups; by the time they disbanded, they had sold more than 20 million records worldwide and had played in more than 700 arenas and festival concerts. "All Right Now" remains a staple of R&B and rock, and has entered ASCAP's "One Million" airplay singles club.
