Rock Pig
I was given the fridge magnet pictured on this page by a very good friend a few years ago, and was slightly surprised, and underwhelmed at the time, as I am sure my face gave away...
But now I am putting out pig-related geocaches, it has been a great source of inspiration.
This is a classic, but I have to put it in the so-so category within my own personal taste. It has 'Pigs' in the title so I have to use it. It is great in so many ways, but what really, really, really gets to me about this song is the use of the word 'masses' to rhyme with 'masses' - "Generals gathered in their masses./Just like witches at black masses." No!
Although I love these songs, I am over 18, and rock isn't always for children, so if you seek out this music (which I heartily recommend you do), here is my parental advisory sticker:
Please be careful when looking for this cache. There are some parts of the platform that have old barbed wire on them, though not particularly close to where I hid it.
