“Hollywood Sings Country” is a one-hour special premiering tomorrow night at 9 p.m. ET/PT on CMT.

The show shines a spotlight on A-list celebs like Russell Crowe, Robert Duvall, Joaquin Phoenix and Reese Witherspoon who acquitted themselves admirably behind the mic and some B-listers like Steven Seagal, Maureen McCormick and Jerry Springer whose efforts are a little more questionable.
