Side Show, the greatest show the Richard Rodgers has ever seen? I'm not sure it makes the top 20, for a theatre that housed the original productions of Guys & Dolls, How to Succeed in Business Without Really Trying (and the revival), One Touch of Venus, Damn Yankees, 1776, Chicago (and the revival), Finian's Rainbow, Raisin, the '71 No No Nanette, New Girl in Town, Redhead, Lost in Yonkers, Nine, Fences...
Begin at the beginning and go on till you come to the end: then stop.
