El Paso is a song by country singer Marty Robbins.
There are three versions of the song: the original (which at 4 minutes, 38 seconds is longer than the standard radio length for country songs at the time, but is the best known and most popular version), and two edited versions for radio play.
The song is set in the Old West, the singer a cowboy who regularly visits "Rosa's Cantina" and falls in love with Feleena, a young Mexican dancer. He engages in a gunfight with another man for Feleena, he wins but is now an outlaw and escapes to New Mexico (but not before stealing a horse).
Now wanted for murder and horse theft (both of which were capital offenses at that time), he is unable to escape his feelings for Feleena and returns, and is fatally shot by a posse, but makes it to the cantina and dies in Feleena's arms.
