I wouldn't mind "implanting" another Irish-oriented band to our lands, but according to
this site they are (or rather were) from Moscow. Also their accent is everything but Czech. (And no matter how I strain my ears, I cannot hear any Czech anywhere in the song - are you sure you were not hearing things?

)
By the way, there are many other songs by Irish/Celtic bands at the above mentioned site as well - not Pogues covers, and not only by bands from Russia.
