It’s definitely not a sped-up “Volga Boatmen”. I know what astorian’s referring to, and the comparison is a huge stretch. It sounds like some hopak or trepak.
I can’t find a Granny cartoon, but are you sure the music used isn’t from Raymond Scott’s adaptation of the Mozart, titled “In an 18th Century Drawing Room” (which I have definitely heard in other Looney Toons)? - YouTube
That I remembered wrong :smack:, the Volga reference was not the correct one, so I prefer the second choice, I do remember that Termite Terrace was capable of composing tunes when needed, as in One Froggy Evening, the song the Michigan Rag was not an old tune, it was made for the short by Milt Franklyn, Michael Maltese and Chuck Jones.
There is still a third choice as mentioned by the posters on that thread: That Carl Stalling grabbed it from stock music.
