Prince stunned fans at a gig in New York on Thursday night (22Aug13) when he took to the stage for an impromptu performance with his former backing group New Power Generation.
The band is playing a six-show residency at the Big Apple's City Winery, and promised fans a special guest appearance every night.
Thursday's crowd was thrilled when the Purple Rain rocker graced the stage sporting an afro and carrying a gold cane in the early hours of Friday morning (23Aug13).
Prince played Musicology, Don't Stop 'Til You Get Enough and Nothing Compares 2 U, the track made famous by Sinead O'Connor.
New Power Generation backed Prince from 1990 to 2009.
