John Mayall, OBE (born 29 November 1933) is an English blues singer, guitarist, organist and songwriter, whose musical career spans over sixty years. In the 1960s, he was the founder of John Mayall & the Bluesbreakers, a band which has counted among its members some of the most famous blues and blues rock musicians.

Born in Macclesfield, Cheshire in 1933, Mayall was the son of Murray Mayall, a guitarist and jazz music enthusiast. From an early age, John was drawn to the sounds of American blues players such as Lead Belly, Albert Ammons, Pinetop Smith and Eddie Lang, and taught himself to play the piano, guitars, and harmonica.

Mayall spent three years in Korea for national service and, during a period of leave, he bought his first electric guitar. Back in England, he enrolled at Manchester College of Art (now part of Manchester Metropolitan University) and started playing with a semi-professional band, The Powerhouse Four. After graduation, he obtained a job as an art designer but continued to play with local musicians. In 1963, he opted for a full-time musical career and moved to London.
