I have only ever seen the movie of Anything Goes--that Donald O'Connor-Bing Crosby-Zizi Jeanmaire-Mitzi Gaynor extravaganza--so I apologize if this is clearer in the stage show.
All we learn about the plot of the show they'll produce is that it involves two gentlemen and two ladies. Presumably romantic hijinks ensue. There is no suggestion of revivalist tendencies. Sky Masterson is not in this show.
So what gives?
