How could I get the opportunity to see Swan Lake? 🦢 ?

Swan Lake is a ballet with music by Tchaikovsky. I'm not sure if you mean you just want to see this ballet, or if you want to see a particular production by a particular ballet company which is in Russia. But anyway, Swan Lake is one of the most popular ballets so it's performed all around the world. I'm sure there are live streams of ballet productions happening, otherwise once restrictions ease some more you could go and see the production that's closest to you, or even eventually travel to Russia to see it.

Putting aside the obvious answers. There are some really excellent companies (including those in Russia) that are streaming ballet for free or pay-per-view! 

I cannot believe this is a serious question 

Swan Lake is performed all across the world. 

It is likely that there will be performances of 'Swan Lake' not far from where you live, if you live in  a 'western' country.   It is one of the most popular ballets.   If you like the figures on your music box, be sure to check that it is a 'traditional' performance. You might not like a 'modern' rendering.

The tickets will not be cheap, but definitely cheaper than going to Russia to see a performance.

Google  "ballet companies" and your nearest city, or "swan lake ballet" and your nearest city. 

During the Covid-19 pandemic, the ballet companies might not be performing right now; but one never knows if someone is putting on an outdoor performance of something to entertain a limited number of people.  (Some musicians and actors have performed outside nursing homes. The patients sit inside at their windows or outside on the lawn - suitably spaced - while the artists perform.)

There are also videos. Check "Swan Lake" on YouTube.

Oh, well, the reason it's only in Russia, you see, is to make sure the riff-raff, like yourself, can't get to it. And that's good, in my opinion. Can't have the great unwashed attending The Swan, can we? No.

What do you mean - it's in Russia?

Swan Lake is performed all around the world.

I'm in the UK and I've seen it here.

Google 'ballet companies' in your country.
