B&W: Murderer on Ship Turns Out To Be Piano Player

I'm not giving you much to go on, but it's all I remember! What's the name of this film? I saw it when I was a kid.

It's black and white, and everyone's on this ship, it's claustrophobic, scary and the ship is full of weirdos. In the ship's bar there's a weird guy playing the piano all the time, but you realize its an auto piano playing itself, and he's used the sound as cover to sneak off and kill someone.

Thanks.
