Yes! I worked with a 4th Grade Language Arts class in Mexico to write "Jaime Mincus: The Musical." I had the kids once a week for music class, but with their homeroom teacher, we developed an overlapping schedule. The students wrote the show and made up their own songs. ("What a Nerd is Jaime Mincus" and "Why Do We Have Boys/Girls" were some of my favorites.) The classroom teacher used the time in LA for the kids to write book and lyrics and morning meeting to discuss progress. I used music class to rehearse and compose music. At the end of the semester, we peformed the show for the entire school. Five years later, every single one of those kids still remembers the songs and most are involved in theater at their high school. In addition to being a fantastic experience, the kids learned to share responsibilties, recognize each other's talents, found ways to make sure everyone was included and felt important... truly worthwhile. This experience was possible because of the relationship I had with the classroom teacher as well as the combination of the students in his class that year, but now that I've done it, I'm sure it can be replicated.
