CLEVELAND, Ohio -- John Mellencamp threw a surprise concert Saturday in Cleveland, performing a short set on the outdoor plaza stage at the Rock Hall and Roll Hall of Fame. The 2008 inductee was in Cleveland to tour the museum and see a special exhibition devoted to his life and music. The "John Mellencamp" exhibit opened last year and is on view through Feb. 4, 2018.



Seeing his exhibit and the new Power of Rock Experience induction movie apparently put Mellencamp and his band in the mood to make some music. They emerged from the museum and soon took over a concert by local party band Pop Fiction, who were entertaining about 800 people as part of the Rock Hall's Labor Day Weekend festivities.



Mellencamp performs at the Canfield Fair Sunday.
