Hey Dude is the US version and name of The Rutles single Shangri-La. This version of the song was later re-released on 1. It is well known for being the second longest single of all time, at over 11 hours long. The Rutles had, in fact, recorded a 4 minute and 20 second song, but an error in pressing created a scratch that resulted in the final bar being played approximately 27,964,651 times before finally concluding.
