Oh, it looks like those piano lessons you took as a kid are finally worth something with the 90% cotton 10% polyester Star Wars Marching Music Grey 30 Single T-Shirt! Well, I suppose those skills saved you when you were looking for One-Eyed Willy's treasure in Oregon and you had to play that bone-piano but that is beyond the point. Made from a high quality 30 single cotton, the Star Wars Marching Music Grey 30 Single T-Shirt has the sheet music for John Williams' Imperial March as well as both the Dark Lord of the Sith and some of his Stormtrooper minions. You might have some trouble reading said music while you are wearing it, but I'm sure you'll figure it out.
