John Mayall & the Bluesbreakers were an English blues rock band led by multi-instrumentalist, singer and songwriter John Mayall. The band has been influential as an incubator for British rock and blues musicians. Many of the best known bands to come out of Britain in the 1960s and 1970s had members that came through the Bluesbreakers at one time, forming the foundation of British blues music that is still played heavily on classic rock radio. Among those with a tenure in the Bluesbreakers are guitarists Eric Clapton, Peter Green and Mick Taylor, bassists John McVie, Jack Bruce and Tony Reeves, drummers Hughie Flint, Aynsley Dunbar, Mick Fleetwood and Jon Hiseman, and numerous others.

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.
