How can I buy a bottle of Night Train Express wine for a special present for my best mate if I live in the UK?

It is special because we are both old school Guns n Roses fans and both grew up with listening to them and have always said we would love to get hold of a couple of bottles because of the G n R song "Nightrain". Problem is it only seems to be sold in America and no one exports it! I need some help please!
