If you go to YouTube and search for Stepjmil you'll find several samples. I've been singing and writing songs long before Doug invited me to join Celtic Coyotes. Some of my songs are social justice, peace, and environmental efforts. Some are for worship. Some are just for fun. Some come from someone's suggestions.
"A Green New Deal" is one song on YouTube if you search for stepjmil.
A song for worship (a hymn). The score is available.
