The Candy Mountain Cave song.
Lyrics:
Oh, when you're down and looking for some CHEERING UP Then just head right on up to the candy mountain cave When you get inside you'll find yourself a CHEERY LAND Such a HAPPY and joyful and perky merryland They've got lollypops and gummy drops and CANDY THINGS OH SO MANY THINGS that will brighten up your day It's impossible to wear a frown in CANDY TOWN It's the MECCA OF LOVE, the candy cave They've got jelly beans, and coconuts with little hats, Candy wraps, choco bats, it's a wonderland of sweets. Ride the candy train to town and hear the candy band, Candy bells, it's a treat as they march across the land. Cheery ribbons stream across the sky into the ground, Turn around, it astounds, it's the dancing candy tree. In the candy cave imagination runs so free, So now Charlie please will you go into the cave.
For context of the Candy Mountain Cave song, you have to see:
Charlie the Unicorn.
