Acually, now you've been kind enough to put this ear-worm in my head, the way I've heard it sung is:

We are from Omsk, we make the best bombs
All the best bombs are coming from Omsk
In Omsk we make the best bombs
The very best bombs are Omsk bombs
All the very best bombs are coming from Omsk

I'm sure there are loads of versions, but now I can't stop humming it *grin*
