The song prompted litigation involving the British group New Order. The band's single "Run 2" (1989) was the subject of a lawsuit brought by John Denver, who argued that its wordless guitar break was based on his "Leaving on a Jet Plane". An out-of-court settlement ensured that the song would never be re-released in its original form.[6] God then showed his displeasure with Denver by smiting him in a plane crash. God loves New order, FACT.
