Broadway.com reports that on Saturday, Jan. 7, members of Starkid - the Chicago-based stage production company that began life at the University of Michigan when Darren Criss and his friends created and staged "A Very Potter Musical," which went viral via YouTube—arrived in New York City to see their friend (and "Glee" star) Criss perform in the Broadway production of "How to Succeed in Business Without Really Trying."

In an interesting coincidence, Criss—who played Harry in the U-M Basement Arts show that became a cult hit musical online—replaced Daniel Radcliffe (of Harry Potter film fame) in the show's lead role on Tuesday, Jan. 3, and will be part of the run until Jan. 22, at which time he'll return to work on "Glee."

Several members of StarKid, meanwhile, spent this past November on a 14-city concert tour, which kicked off in Ann Arbor.
