Try to be a little bit objective about this. I'm talking musically not lyrically.
1) La Marseillaise-- French national anthem. Written by Rouget de Lisle during the time of the revolution and then later arranged by Berlioz. This is the best arrangement and the one most frequently used. Usually two stanzas are sung.

2) God save the Tsar-- anthem of Imperial Russia prior to the revolution. In the version shown there seems to be some disagreement as to whether or not it is the actual anthem, which of course it isn't. But many people are standing as if it is.

Here is another version of God save the Tsar sung by a group of Cossack cultists pining for the wonderful days under the tsar. Well, now they've got Putin. I hope they're happy.

3) I don't know. Maybe O Canada or God Save the Queen.
The Star-Spangled Banner is down there somewhere. Francis Scott Key wrote the lyrics not the music, which is an Old English drinking song. Not really good music though.
Anyway, maybe you've got some other ideas or anthems I'm not familiar with.
