A covers tree

The Patnáctiny situation has to be structured:

1. Original: beFour - How do you do? from 2007 [wiki]
     1.1 English cover => Boom - How Do You Do? klip, Official UK version
     1.2 Dutch cover => Djuli - How Do You Do [the strangest language for song and singing I've ever heard]

     1.3 Russian cover => !BUM! - Kanikuly 

          1.3.1 Code Red - Kanikuly 2007
     1.4. Czech cover => LuŠtěLa - Patnáctiny
          1.4.1. ČeskáBomba - Osmnáctiny
          1.4.2. Umbrtka - Šedesátiny

I bet there are a lot of more covers on YouTube.
