Kevin Spacey joined Billy Joel on stage for a performance of Joel's classic song Piano Man. See a clip of the House of Cards star singing and playing the harmonica here!

The performance was part of a PBS tribute show Billy Joel: The Library of Congress Gershwin Prize and other stars such as Tony Bennett, Josh Groban and LeAnn Rimes also appeared to honour the musician.
