Tonight is the opening night for the new Beatles musical, but as the curtain rises tonight, there’s some real drama playing out off stage.

The new Beatles musical, Let it Be kicks off its five month run tonight on Broadway at the St. James Theater, but according to the New York Times, the producers of the show are being sued by the group behind a different Beatles show, Rain. They claim that the new show is a rip off of their show.

The suit says that Let it Be is an offshoot of Rain and the producers agreed to split everything 50-50, but the deal ran out just before Let it Be started playing in London last year. The team behind Rain says that they don’t want Let it Be to be shut down, but rather are asking a judge to reinstate the 50-50 agreement.

Let it Be will focus heavily on the music of the Beatles, their time at the Cavern Club in Liverpool, Beatlemania and their later years apart.

The show runs through the end of December.
