Dedication: The Very Best of Thin Lizzy is a compilation album released by rock group Thin Lizzy in 1991. The only previously unreleased track was "Dedication", which was reconstructed after Phil Lynott's death using an old 8 track demo recording of the song (originally recorded around 1985) to provide the bass and vocal lines, with new guitar and drum parts added by Scott Gorham and Brian Downey.
