President Obama appeared hesitant to sing publicly for the second time in 2012 at a White House event Tuesday night.

But he obliged the request by blues legends Buddy Guy and B.B. King, singing a few lines of “Sweet Home Chicago.”

“Come on!” Obama said when Guy asked him to sing as he was soliciting applause for the final performance.

“You done started something. You gotta keep it up now,” Guy said.

“You can do it! ” King added.

“Oh come on, baby don’t you wanna go,” Obama sang, while Mick Jagger, another performer at the event, clapped along.

Last month, video of President Obama singing a few notes of Al Green’s “Let’s stay together” went viral. Green was performing at an Obama fundraiser.

The event Tuesday night was held by the Obamas to honor the blues in conjunction with Black History Month. The Obama White House has hosted a series of similar concert-like performances to honor jazz, Latin and country music.

Here’s a look at Tuesday night’s set list, according to the pool report.
