A few steps:
1) Solve the puzzle to reveal the cache that contains the clue
for the final coordinates
2) Find the first cache to retrieve the clue to figure out the
final coordinates
3) Figure out the final coords and find the cache.
The melody of "Good Morning to All" was converted many years ago
into the most recognized song in the English language. Take the
shorter name of that song to help you find the cache that contains
the clue to help you get the coords for this cache.
The GC Code for the cache is GCXX21M
where XX = the number of letters in the name of the song
multiplied by 2 then plus 2.
Once you find the cache GCXX21M, retrieve the clue written on
the underneath side of the lid of that cache.
Using the clue, the final coordinates are:
40° 27.AAA
086° 55.BBB
where AAA = number of letters in the entire clue multiplied by
10 then minus 50
and BBB = the number of letters in the first two words of the
clue multiplied by 10 and then add 6
