Former TNT frontman Tony Harnell is currently on tour as a solo act providing support for Stryper.  When the show got to BB King Blues Club in New York last week, Harnell and Stryper frontman Michael Sweet had a surprise for the crowd, as the two metal singers joined forces on a cover of the Judas Priest classic "Breaking the Law" as well as a cover of "More than a Feeling" from Boston, which Sweet was a part of for several years.  Check out some decent fan-filmed footage of both performances below.
