"Crazy Arms" was a piece of Earth honky-tonk music from 20th century America.
It was playing on the jukebox in the Pine Tree Bar and Grill when it was first visited by the Vulcans T'Mir and Mestral in 1957. (ENT: "Carbon Creek")
The song was recorded by Ray Price in 1956. For the Blu-Ray and international versions of the episode, the song was replaced with "Gently Falls" by Dave Colvin.
