There’s a provocative detail in this article about astronaut Chris Hadfield’s cover of Major Tom recorded in space :

“The Larrivée Parlor [Hadfield’s guitar] on the ISS was purchased at the local Guitar Center in Southern Florida and there are actually two of them,” Larrivée told SPACE.com. “The other stays on the ground at NASA so they know what’s up there.”

They really are prepared for a “We gotta find a way to make this fit into the hole for this using nothing but that.” scene!
