Document 4: Highwayman (song): "Highwayman" is a song written by American singer-songwriter Jimmy Webb, about a soul with incarnations in four different places in time and history: as a highwayman, a sailor, a construction worker on the Hoover Dam, and finally as a captain of a starship. The song was influenced by the real-life hanged highwayman Jonathan Wild. The dam builder verse alludes to the deaths of over one hundred men during the construction of Hoover Dam near Boulder City, Nevada. Webb first recorded the song on his album "El Mirage", released in May 1977. The following year, Glen Campbell recorded his version, which was released on his 1979 album "Highwayman".

Their first album, "Highwayman", became a number one platinum-selling album, and their version of the song went to number one on the Hot Country Songs "Billboard" chart in a twenty-week run. Their version earned Webb a Grammy Award for Best Country Song in 1986. The song has since been recorded by other artists. Webb himself included a different version on his 1996 album "Ten Easy Pieces", a live version on his 2007 album "Live and at Large", and a duet version with Mark Knopfler on 2010 album "Just Across the River".
