ISIS at the Eurovision
This is a particularly sharp satire.
Sweden, the hosts of last night's Eurovision are perhaps the most extreme case of left wing liberalism, resulting in a moral blindness on the Middle East & Israel, best exemplified by their foot-in-mouth Foreign Minister Margot Wallström.
Abbu, being a play on Abba, Sweden's greatest Eurovision and pop-music success ever.
The four severed heads are those of that famous four Abba members.
The song references the Muslim mass-migration/invasion of Europe, encouraged by Sweden, the terrorist murders in the Paris Hyper-Kascher food market and Islamic homophobia.
And a catchy tune to boot. (Better IMHO than most of the real Eurovision songs).
