VIDEO: John Oliver Sings to Coal CEO Robert Murray in Epic Musical Number

Over the past two years, John Oliver has been involved in a lawsuit with coal company CEO Robert Murray, after Oliver called Murray a "geriatric Dr. Evil" and made fun of his energy corporation during a segment in June 2017.

Recently, Murray dropped the suit against HBO. During this time, Oliver was unable to make jokes about Murray or the lawsuit, but now that the suit has been dropped, Oliver is going all out.

During last night's episode of Last Week Tonight, Oliver ended his show with a huge musical number about Murray.

The number featured Broadway's Brian d'Arcy James, and was staged by John Carrafa.
