Before Marilu Henner became a household name on Taxi, she had a thriving career in musical theater. This week, we spoke to the always busy Marilu about the original \u201cdown and dirty\u201d version of Grease she never imagined would inspire a smash hit, happy memories of Joe Allen and other theater district haunts from her early years on Broadway, and the painful lengths she had to go to in order to keep a straight face opposite Danny DeVito. We were also fortunate enough to discuss her personal challenges as chronicled in the best selling 2016 book Changing Normal: How I Helped My Husband Beat Cancer, and how the whole concept of \u201cchanging normal\u201d is so relevant to this moment.
