Philadelphia Mayor Michael Nutter “made a surprise appearance onstage with The Roots and showcased his rap skills to a cheering crowd with his performance of ‘Rapper’s Delight,’ the Philadelphia Inquirer reports.

“Following his rendition of The Sugar Hill Gang’s immortal classic, an out-of-breath Nutter emphatically dropped the microphone to the delight of the cheering crowd gathered on the Ben Franklin Parkway.”
