All I can say is WATCH OUT! Now I'm going to feel compelled to make all kinds of songs that don't truly have the right number of syllables to match the tune, but it's not going to stop me from creating! Ha!
I created a song for Shared Reading called We Celebrate Presidents' Day to the tune of Battle Hymn of the Republic. (In case you aren't familiar with the tune, you can find a midi file here.) I created three copies to be used. Click on the picture below to purchase this song through my TpT store.
