Uh Oh-Look Who's Suing Dollywood!

Good grief! 

The writer of "Christmastime Is Here," a song from A Charlie Brown Christmas, is suing Dollywood for using the song in their holiday presentation "Twas the Night Before Christmas."

Lee Mendelson's production company, which owns the rights to the song, wants the theme park to pay up for all the years they've used the song without permission -- since 2007. They also want Dollywood to stop using it until a deal is reached. (TMZ)
