Don't quit your day job! President Barack Obama broke into song last night at the Apollo theater in Harlem, and busted out a couple of lines from "Let's Stay Together" by Al Green.

Add this to "Obama's Greatest Hits" which also includes his version of Lady Gaga's "Born This Way" which went viral a few weeks ago.

"Don't worry, Rev, I cannot sing like you," he told the audience, which included the Rev. Al Green.
