ABBA madness in Poland

Major Polish cities will have an outdoor New Year party.  Two of the biggest parties will feature ABBA -impersonators:

• The party in Warsaw is organized by Polsat (a Polish TV station).  The stars there include Abbacapella (apparently a German band).
• The party in Wroclaw is organized by TVP 2 (another TV station). ABBA music will be performed there by a Swedish group Arrival. An it seems that Modern Talking is the biggest star there.

ABBA tribute bands are listed here (Arrival is there but not Abbacapella). The list is longer than I expected although I know that I shouldn't be surprised.
