After curtain calls, I bid the LaSalle Bank Theatre farewell because it may be a long time before another production plays here. Jersey Boys has an announced run of six months, but nothing else has been booked into the house for the rest of the season or for that matter, for any time beyond the season. Like Wicked before it, Jersey Boys, the current second-highest grossing show with Broadway (after Wicked) and the one that commands the highest average ticket price, may be settling in for a deservedly long run in Chicago. The Chicago cast, most of whom were with the show for four months in San Francisco before coming here, are every bit the equal (and in some cases maybe better) than the original cast that originated the parts of Frankie Valli and The Four Seasons on Broadway.
