"Dead Man Walking" is a song written by David Bowie and Reeves Gabrels and released as single from the 1997 album Earthling. It was a number 32 hit in the UK.
The guitar riff used in the intro dates back to the mid-1960s when Jimmy Page taught this to Bowie. Bowie later used it for his song "The Supermen" in 1970, and revived it 25 years later for "Dead Man Walking".
