Glad to share and thanks for the kind words! I do not have the info handy on obtaining a usage license for Christian music in chalk programs. Those fees are covered by my employer so I have not had to deal with the nuts and bolts of that.
However, I do know of chalk artists who have sent emails directly to different musical artists (usually via the Contact link on the musician's website), and have been granted permission to use the songs in chalk tracks - with no fees involved!
Sometimes it's just worth asking, eh?
Best,
Kerry
