US President Barack Obama sang with blues legend BB King at an event at The White House yesterday night (February 21).
The impromptu performance followed Obama's recent rendition of Al Green's soul classic 'Let's Stay Together' at a fundraiser in New York last month.
Obama took the microphone to thank BB King and Mick Jagger for performing, reports TMZ, and was then convinced by guitarist and singer Buddy Guy to sing some choice lines from 'Sweet Home Chicago'. Watch his performance below:
