I'm not sure which would be scariest - ABBA covers in the style of Sabaton or Sabaton covers in the style of ABBA.
Either would be worth a listen once though ...
Now you mention it, I think they did that at Southampton as well ...I can only say that being at a Sabaton gig where the intro was "The Final Countdown" IN FULL! on the PA was the most Swedish thing I ever witnessed.
ther;s no way that sabatin shitty crap is appearing below my subnarture
