To celebrate Behind The Curtain's over 500 episodes, Backstage Babble's Charles Kirsch turned the tables on Rob and Kevin and made them the guests of honor.

The boys look back on how they met, their favorite guests, their oddest interviews, and why they are passionate about preserving the oral histories of Broadway's hardest workers.
