Justin Timberlake stopped by the White House on Tuesday as part of a tribute to Memphis soul music. The latest round of In Performance at the White House featured Timberlake leading a sing-a-long of Otis Redding's "Sitting on the Dock of the Bay," with President and Mrs. Obama seated on the front row singing along.

The full night of performances, which airs April 16 on PBS, includes appearances by Mavis Staples, Alabama Shakes, Booker T. Jones, Charlie Musselwhite and Sam Moore.
