Mozart's Trilogy

I have just formed a Mt. Dulcimer group with three of my students.  We call ourselves: "Sweet Strings" Our first gig will be part of a talent show at our church.  In the program it says: "Sweet Strings" will now be playing what they call: Mozart's Trilogy. We then will proceed to play and eventually ask others to join us in singing: Twinkle, Twinkle, Little Star; Baa Baa Black Sheep; and The ABC Song. These lyrics were all set by others to this French Folk Tune that Mozart set down originally for piano music. I pass this idea on because some you might like to use it too.
