Daniel David Kirwan was a British musician whose greatest success came as guitarist, singer and songwriter with the blues-rock band Fleetwood Mac between 1968 and 1972. He released three albums as a solo artist from 1975 to 1979, recorded albums with Otis Spann, Chris Youlden, and Tramp, and worked with former Fleetwood Mac colleagues Jeremy Spencer and Christine McVie on some of their solo projects. He was inducted into the Rock and Roll Hall of Fame as a member of Fleetwood Mac in 1998.

"Man of the World" is a song recorded by Fleetwood Mac in 1969, and composed by vocalist and lead guitarist Peter Green. After the group signed to Immediate Records that year, the label collapsed shortly after the single's release. As such, "Man of the World" is the only Fleetwood Mac single under the Immediate Records label.
