Soldiers of the Soil
Ethel and Gracie find themselves fired as switchboard operators at the Hotel Royale, but not before they believe that the hotel manager is in fact stealing stock to sell on the black market. As such they decide to disguise themselves and play amateur detectives to gain evidence of what he is up to even if they end up stumbling into one mess after another in trying to get the evidence.
I have to be honest and tell you that before watching "Up with the Lark" I had never heard of Ethel Revnell and Gracie West but from what I understand is that they were music hall performers who during WWII would appear on the radio. In fact you don't even need to know that because within 20 minutes of "Up with the Lark" starting you are treated to a mix which features a musical skit which sounds like some thing a music hall act would sing, which is delivered with plenty of gusto and face pulling, and then there is plenty of word play comedy which would come across nicely on the radio. But I have to say that whilst the innocence of "Up with the Lark" is pleasant it is only the sort of bygone movie which ends up as light hearted background entertainment as there is nothing in this which really grabs you.
What this all boils down to is that "Up with the Lark" is a fun distraction with plenty of innocent humour and charm. But beyond some musical scenes and skits this doesn't have a great deal about it, well unless you are fans of Ethel Revnell and Gracie West.
