Something from the boys has a very debonair quality as they tell of their duocareer in collaborating on books and lyrics for musical comedy and prove that Plum and Guy had a lovely time in their friendly profession. Their first meeting and first play --and then from Childs to the Knickerbocker, the Ritz Carlton, the Savoy -- and back to Childs when their baby was a ""floperoo"" rather than a ""socko"" -- and all the people along the way. There was Kern when intimate shows played the Princess; Erlanger led to the unpredictable Savage; there was Marion Davies, Dillingham and Ziegfeld; Marylin Miller, Irving Berlin, the Astaires, Gershwin take their places as do Gertrude Lawrence, Jimmie Walker and Betty Compton. It was top of the world when their luck was in -- and lots of turkey feathers when it wasn't, but the twenties were good to them and when the thirties had a depressing effect -- there was Hollywood. Vamp till ready for this extravaganza with its transatlantic flavor, its breathless (rather than deathless) picture which is never marred by pomp or circumstance or dreary drabness, its loving roll call (Oh Kay, Sally and more and more) and its Bertie Wooster style. Real fun.
