Kazakhstan greatest country in the world.
All other countries are run by little girls.
Kazakhstan number one exporter of potassium.
Other countries have inferior potassium.

-- Kazakhstan National Anthem (not!), by Sacha Baron Cohen a/k/a Borat

Do we know when this was done? I would guess it was in the immediate post-Soviet era: older cars, older style of clothing, shiny new building in an empty field, Soviet-style music; and I think Chernomyrdin appears in the closing section, who led Gazprom from 1989-92. During the Soviet era this would have been a typical thing for any large enterprise to have, and this may have been an attempt at immediate post-Soviet "rebranding" of a newly "Russian" company.

I would guess that any similar "anthem" for Gazprom today would feature a driving metal rock beat, and images of Russian power rather than friendliness.
