Last night, President Obama and the First Lady hosted the 10th concert in the In Performance at the White House series. Justin Timberlake, professional charmer and sometimes-crooner, encouraged his hosts to join him for Otis Redding's "Sitting on the Dock of the Bay." Timberlake appealed to the whole ragtag bunch of fancy concert-goers by cajoling: "Mr. President, everybody, come on!"

This is not the first time Timberlake and Obama have worked collaboratively on a track; the President covered "SexyBack" in January 2013 (not really, duh, but here it is if you're into this sort of thing).

Last night's In Performance at the White House was set to honor Memphis Soul, especially the music produced there in the mid to late 1960s. The concert included performances from a fantastic selection of musicians like Mavis Staples, Sam Moore, Steve Cropper, Booker T. Jones, Charlie Musselwhite, as well as Alabama Shakes. PBS will broadcast the full performance on April 16. More sing-along moments not promised.

Remember this? The best.
