"Old McDonald," "Wheels on the Bus," "I've Been Working on the Railroad," and other stuff like that. These are all traditional songs, songs for which the original author is unknown that have been passed through generations -- and have remained popular for a reason.
My "________, It's Your Birthday" song with a bunch of different names inserted. If you can't find the name of the birthday girl or boy (or woman or man) you'd like to hear, let me know and I'll record a new video.
It all started when a girl got really sick the day I was supposed to play her birthday party. I decided to sing a birthday song for her, but as "Happy Birthday" isn't in the public domain I had to write my own.
I knew other kids and parents would want me to sing the same song to them as soon as I posted that original song so I intentionally made it a flexible composition, one where different names could easily be inserted and that lent itself to being played with different rhythms and in different genre-specific styles.
