Prince (21)

A curiosity that can hardly be solved at all: this name actually appears on a single among other credits and is related to guitar [Guitar Prince], but the actual music has no clue of guitar. And it is also remarkable that this 'credit' does not refer to Prince, even if this has been adopted by his fans respectively the collectors for a long time, and which in turn has motivated bootleggers to include the corresponding tracks on their illegal output.
