Another Day, Another Marvin

Today, I conducted a very contentious six hour mediation. 
The rubric of the case was legal malpractice.  The case was
either going to be a home run for the Plaintiff, with a recovery of as much as
half the proceeds from a very successful album, as well as live performances,
or, on the other hand, a defense home run, with a Marvin case, bereft of the music and of minimal value.
