"Leader of the Band" is a song written by Dan Fogelberg from his 1981 album "The Innocent Age". The song was written as a tribute to his father, Lawrence Fogelberg, a musician and the leader of a band, who was still alive at the time the song was released. Lawrence died in August 1982.
Fogelberg performed the song as an opener for Paul McCartney's Wings in the 1970s.
