As I recall, there were several changes made for the cast album, that had nothing to do with how the material was performed in theatre. If I'm not mistaken, the arrangements and choreography were recreated precisely as possible for Allen for the actual show.
My biggest problem in this revival was with "Frug" which was just a big ole nonsensical sloppy mess in this revival, instead of the clean, crisp, expert choreographic satire I remember from the 1986 revival (as well as the film and "Fosse"). I'm not against change, per se, but when that change renders one of the highlights of an entire show into a meaningless display of wrong-headed, random dancing, it's hard not to wonder just what the creative team was thinking when they did it.
Between that and the utter lack of wit and invention in "The Rhythm of Life" (which is badly blocked and staged and just sits there) and "Big Spender" (which had the feel of a college production trying to cover up for the fact that their chorus really couldn't dance ... and this one COULD if Cilento knew how to stage the number) and the fact that "There's Gotta Be Something Better Than This" never exploded and electrified the stage and nearly stopped the show as the original version did, made me wonder exactly what the point of tossing out the Fosse choreography was, if it wasn't being replaced by something that was at LEAST a tenth as good.
I've seen HIGH SCHOOL productions that have choreography as good as what's passing for "Broadway dancing" on the stage of the Hirshfeld these days, which is criminal considering the talent that's being wasted on that stage.
