Lindsey Kraft (Grace and Frankie, dELiA*s catalog) and Jamie Lynn Sigler (The Sopranos), who grew up together on Long Island, stop by to talk about the simple, catchy harmonies in “Life Support.” Lindsey was never in a musical as a kid, but watched Jamie perform in a ton of them and, one time, she got to sit on the edge of the stage with her legs dangling off and do a solo in a show choir Rent-medley. Jamie gives us the scoop on her audition and multiple callbacks to play Maureen at the Hollywood Bowl.
