Mozart and Ode to Joy

Dear forum members!

I hope to find an expert of Mozart on this forum who can answer a question to which google gave no proper response.

Background: a few months ago I heard a radio interview where a Mozart (as I remember a cantata, KV 2xx) was played. One of the melodies in this cantata was the theme of the Ode to Joy.

Since then I want to find this cantata, and I would be very happy if someone here on the forum knows.

Regards,

Stephen


p.s.
Actually what is also interesting to me is that the ode to joy is so connected with Beethoven. I want to listen to the original Mozart melody, and then raise some philosophical questions about the intention of creating a melody, the political use of a melody, what this say about Mozart an Beethoven and so on.
