I was in Friday's opening-night audience for the Mississippi Bend Players' Dames at Sea. George Haimsohn and Robin Miller wrote the 1966 piece's book and lyrics, with music by Jim Wise, and as Augustana College's Brunner Theatre lobby display notes, it's a spoof of the films Gold Diggers of 1933, Footlight Parade, and 42nd Street. The old show-biz tropes it sends up are easy targets, and the tunes are imitative (naturally), but vastly enjoyable. As for the script, it's just one giant, cheerful wink in which continuity and plausibility are irrelevant. Show people playing show people putting on a show is a sea of fun to begin with, and the plot merely dips a toe in the water now and then, leaving the singing and dancing to make the big splash – which, here, they do.
