Dearest maybethistime:
Perhaps I can help. I was in the original production way back in 1937 and although I am something of a dinosaur, I perhaps may be able to shed ssome light.
First of all the libretto. It was terrible back in 1937. During out-of-town tryouts and even when we played on Broadway we had people come in to help with the libretto. Rodgers and Hart wrote the libretto, but they really did notknow what to do with the characters, which is why the whole play is rather ramschackle and haphazard. I think audeiences in 1937 were more than willing to put up with the absurdities as long as they were guaranteedothe entertainment values, and in the song and dance departments, we provided quite a show! What is even stranger--and funnier--was that the show gave birth to so many song classics, and the audience always greeted the songs with polite applause, and not much else. Today they would be screaming in the aisles! But back then when we had Kern, Rodgers, Berlin, Porter, Schwartz, etc., the audience could pick and choose at random.
I know that there have been different editions of the libretto. From what I gather you will be using the 1937.
There were only three male characters who sang:
Valentine (originated by Ray Heatherton) was 25 years old when he originated the part, but he was supposed to be 16 in the script. He had a mture temorish voice, if memory serves me right. beautifully placed and focused, his voice was called for two of the song hits: Where or When and All At Once.
Gus (originated by Rolly Pickert, I think), was more of a dancing role, although he sang in two of the sprightliest songs of the show, I Wish I Were In Love Again and All At Once. This called for a light tenor voice, although a baritone could probably also do it. But again, the emphasis on the character was more on dance than on singing.
Alfred Drake originated another part, I can't remember which. He only had the song Babes In Arms. Drake was a true baritone with a rich burnish.
Peter, played by Duke McHale, had a few lyrics to sing, but again this was mainly a dancing role.
There was a quartett that backed up Wynn Murray, who played Baby Rose. If memory serves, this group was made up of two tenors and two baritones.
I hope I was able to help. Let me know if you need more information.
With best wishes,
