Billy Joel's April show at New York's Madison Square Garden was Friday. As he has frequently done during his once-a-month residency there, he brought out a special guest.
Actor Kevin Spacey from the Netflix series House of Cards joined Billy for "New York State of Mind." While they sang, Spacey -- who is enough of a singer that he played Bobby Darin in the film Beyond the Sea -- took a selfie with Joel.
The two are longtime friends. Spacey honored Joel in 2014 when he was awarded the Gershwin Prize for Popular Song by the Library of Congress.
