Here is a silly song for the Cub Scouts to sing on Thanksgiving. ZM learned it a few years ago in school. It kind of sticks with you after they sing is over and over for three or four days in a row. 
Use this for any of the Cub Scout music requirements:
Tiger Elective 6 – Song Time: Along with your adult partner, teach a song to your family or to your den and sing it together.
Wolf Elective 11 – Sing Along: Learn the words and sing the first verse of three other songs, hymns, or prayers. …
Music Belt Loop Requirement 2: Learn a song with at least two verses and sing the verses to your den or to an adult family member.
