Yup.  Here’s the scoop from the author of the book and blog "Sweet Jesus, I Hate Bill O’Reilly" (gotta love that name, by the way):

In the book "Sweet Jesus, I Hate Bill O’Reilly", we discussed the possibility of a musical theater production. We even went so far as to throw together some lyrics. Well kids, in the race to the stage, we’ve been beaten to the punch… and by a guy named Igor, no less.

Mackris v. O’Reilly is the new work by Igor Keller. The oratorio (which is basically an opera without the scenery), is for a 31-piece chamber orchestra, 32-voice chorus and three soloists, directed by Kris Falk.

The libretto is comprised of the original court document and O’Reilly’s on-air settlement announcement. Imagine a two-hour neo-baroque extravaganza including seven chorales, two madrigals, three choruses, four recitatives, two instrumental entrances and numerous arias dedicated to the sexual exploits of the most popular man in cable news.
