is the original English title. Nothing to do with trombones, this must have come in with the Russian words. A cello in the original:

It isn't from "Our Miss Gibbs" and isn't by Caryll and Monckton, but by W.D.Cobb and J.H.Flynn. Both this song and Our Miss Gibbs were associated with George Grossmith about 1909.

Adrian, what a surprise! In Russian context this very melody had been most associated with Our Miss Gibbs than any other. It was performed

and even parodied

dozens of times and each time it was noted that it comes from Our Miss Gibbs! But how did this melody come associated with it?

Well, I'm surprised myself - to discover that George Grossmith's recording of this song was labelled as from "Our Miss Gibbs" so it was obviously interpolated into the musical, though it doesn't apparently appear in the score.

It was a US song, originally made famous there by Blanche Ring. I didn't know it was so famous in Russia in these various forms.

So, it comes out that "Yip I Addy I Ay", created in the US, was included in Our Miss Gibbs later, but still in the West, and then, in this "enriched" form, this operetta came to Russia, where the names of the original authors vanished completely?

Yip I Addy I Ay!
(aka "Yip-I-Addy-I-Ay" and other variations)
Written by John H. Flynn and Will D. Cobb, 1909
Introduced in the stage musical "Our Miss Gibbs"

Yes that's right. Both the song and the musical seem to date from 1909. Maybe Grossmith had had such a success with it on other stages that they decided to add it from the start. But unlike some songs by other composers that were added to musicals, this doesn't seem to be in the official list of titles.

Adrian, thank you so much for the precious help! I've modified the information in all the files that contain this melody

Though I think you found out all the facts in the end!

Operetta's title is "Our Miss Gibbs"
