As How I Met Your Mother ends its amazing nine-season run, stars Neil Patrick Harris, Jason Segel, Alyson Hannigan, Josh Radnor and Cobie Smulders joined host James Lipton for an epic episode of Inside the Actors Studio. There were plenty of HIMYM laughs, insights and touching moments…but forget about all that because the most important part was when Harris (as Javert) and Segal (as Jean Valjean) sang “The Confrontation” from Les Miserables. OK, they’ve done it before, but it’s never been this legendary! If you had fun watching Harris sing in this, you're in luck. The star just began performances in Hedwig and the Angry Inch on Broadway on March 29.
