Third in the Christmas Bits and Pieces series. Not at the published coordinates. Solve the puzzle below to find the cache.
First, solve the puzzle above to give you a series of 33 characters (which includes 2 digits). You'll need to add an extra character between rows 1 and 2, it should be obvious which. Next you'll need to identify 9 different Christmassy tunes.
Assume N51 19 and W 000 25. The cache can then be found at:
H*A*(P+P)+Y
(C+H+R)*(I+S+T+M)+A-S
Where:
M=I-S*T
P=A+S+T*2
Y=A-R+D
In a break with my tradition (but in keeping with another 
) there are certificates for the first 12 finders, and a small stocking filler type prize for the FTF.
