Nothing sings pirate more than this song that can be traced back over 100 years. "Dead Man's Chest" (also known as Fifteen Men On A Dead Man's Chest or Derelict) is a fictional sailor's work song from the novel Treasure Island(1883), and a later expanded poem by Young E. Allison (1891). . Some researchers believe Stevenson based the shanty on an actual song. With several Jolly Roger's (pirate flags) to choose from we chose the flag of Calico Jack, he was an English pirate captain during the early 18th century. Why? well look at it - its seriously bad !@#$%^&* :)
