Two things were in my head when I left the Cadillac Palace Theatre in Chicago’s Loop the other night after seeing the show for the umpteenth time. One was that the place was packed to the rafters, which is notable not only because this particular title has been touring for so long, but because there by now have been several local professional productions of the title. (An especially good one, for the record, was Jim Corti’s 2015 staging at the Paramount Theatre in Aurora, replete with the iconic “Les Miz” turntable that now is missing from the revised touring production at the Cadillac Palace.) But not only does that not matter, clearly, but all those stagings in Lincolnshire (2008) and Oakbrook Terrace (2014) likely burnished the waif’s brand and increased the audience’s desire to see the show again. The score is that appealing to such a broad swath of folks.
