Go to Mystery Melody tune to hear the song played by accordion (no words). To my knowledge, this is the only song (in any language) which actually mentions a geographical position, thus it may be of some interest to the Geocaching community.
To log this cache, you must identify the song in question. The location of the cache must then be calculated as follows:
Take the number of degrees latitude mentioned in the song and call that number xx. (Any further details are ignored. We don't care if it is N or S. xx is a positive whole number between 00 and 90).
Take the number of degrees longitude mentioned in the song and call that number yyy. (Any further details are ignored. We don't care if it is E or W. yyy is a positive whole number between 000 and 180).
nnn = 4 * xx + 17
eee = yyy + 4
The cache box is located at: N 55°41.nnn' E012°26.eee'

All successfull logs will be rewarded with a link to the tune (song) so you can hear it for yourself. PLEASE do not post spoiler information!
The listed coordinates leads you to a convenient parking spot within about 100 meters of the cache location. Here you will find an interesting old water tower and an impressive water pipe.
