Disqualification kaos!

It has been pointed out that song #2 in Semi 1 (Sweden 1973 - Sunny Girl) breaks the rules because the band featured Benny from ABBA, who obviously performed at Eurovision.

I won't disqualify the song; instead, I'll leave it up to individual voters' conscience as to whether they vote for it. Although technically, yes, you shouldn't ;)

Sorry sponsor... but you should have done your homework and/or read the rules :-P
