You are right, i thought the song was much older than that. I recorded it from a toy i had when i was a kid.
I am not sure if this would be legal, im trying to find the date. If it was released 1940 or before then it should be part of public domain. See

So yeah, i need to change the license type. Thanks for the heads up.
