WASHINGTON — I guess you really can call him Wonder Mike.

Philadelphia Mayor Michael Nutter capped off hometown heroes The Roots’ performance at the city’s Fourth of July festival by making a cameo during a cover of the classic “Rapper’s Delight.” It takes about a verse before his vocals get turned up in the mix, but you have to stick around for the mike drop:

To those in the know, Nutter’s skills shouldn’t be that much of a surprise: He started off as a DJ, he told Uproxx in a 2011 interview, and he’s done the song before.
