Sir Michael Philip Jagger is an English musician. He is known as the lead singer and one of the founding members of The Rolling Stones. Jagger has co-written most of the band's songs with lead guitarist Keith Richards; their songwriting partnership is one of the most successful in rock music history. His career has spanned more than six decades, and he has been widely described as one of the most popular and influential leaders in the history of rock music. His distinctive voice, energetic live performances, and Richards' guitar style have been the Rolling Stones' trademark throughout the band's career.

He studied at the London School of Economics before abandoning his studies to focus on his career with the Rolling Stones. In the early 1970s, Jagger starred in the films Performance (1970) and Ned Kelly (1970), to mixed receptions.
