The songs that I have posted are my adaptations of songs that can be found in slightly different forms elsewhere on the Internet. There shouldn't be any copyright problems with any of them.
I have been teaching these songs to my students (aged 6 to 12) in Taiwan for years. They love them and can't stop singing them. Parents have told me that their children kept singing them over and over again all night. They've kept on singing them in my class well into November. Most of them had never heard the original songs before, but quickly picked up the simple catchy tunes. In fact, whenever my students hear Rudolph the Red-Nosed Reindeer they shout, "That's the Halloween music!" Simon Peter Hughes 11:56, October 3, 2010 (UTC)
