Andrew McIan Fraser was a British musician and songwriter, best known as the bassist and co-composer for the rock band Free, which he helped found in 1968 when he was 15. He also founded the rock band Sharks after leaving Free in 1972.

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.
