So, Tina Connolly and Dr. Mary Crowell and I have been for several years now collaborating (at a stately pace) on a 6-episode musical theatre podcast, and sometimes Mary posts pieces to her Patreon.
One of the things we love is that every episode stars a different character (there are six characters in all), and though the theme song is always the same tune, its instrumentals and sometimes its language changes depending on which character is starring in that episode. (One episode is just people meowing the theme in unison.)
This one belongs to Mavis Day’s (Lady Midnight herself) episode, and it’s an open post, free to listen!

“At a stately pace’ made me laugh so hard! Stately it is, and a very delightful collaboration!
