The show, which was hosted by Hammer, was called "Hammerman" and aired on ABC in Fall 1991 during the peak of Hammer's success.
Here's the synopsis from Wiki:
Youth center worker Stanley Burrell (Hammer's real name) owns a pair of magical dancing shoes (which are alive and can speak), which when worn cause Burrell to transform into the superhero Hammerman. He frequently gets advice from his "Gramps", who was a former owner of the shoes and was known as Soulman. While in the guise of Hammerman, Burrell was dressed in MC Hammer's signature purple parachute pants and myriad golden chains.
The show was hosted by the real MC Hammer, who also sang the show's theme song, telling about the origin of Hammerman. Back in the 1960s and 1970s, Gramps (real name unrevealed) was the superhero Soulman, but as he grew older, he grew weaker and was forced to retire. Gramps and his granddaughter Jodie traveled to find the next new superhero. Their search was over when they met Stanley and he put on the shoes.
I remember watching this one occasionally, as it aired at the same time CBS was airing the Teenage Mutant Ninja Turtles, but I remember my childhood best friend would watch this one and tell me about it and if I spent the night at her house we usually watched it the next morning.
Here's a clip of the show's theme song:
Oh Hammer... don't hurt em!
