It seems that Ali chose Hava Na gila music in honor of the Israeli team that died in Munich in 1972. She was Jewish and wanted to express that. She is geting lots of press here and will gets a heros welcome after the 5 do a lot of visits.
Oh wow that's wonderful! Most often, NBC, BBC, and the others (along with interviews with Aly herself) have said she was doing it to salute her Jewish roots (she's had that FX for two years now). I'm glad she's changed it to be a tribute to Munich.
I've always loved it when skaters and gymnasts say something with their programs or routines. It lets me know that they do more than just do gymnastics, or skate.
The interview I heard made it seem it was always a tribute using the music. How can the IOC stop anyone from offering a performance to anyone? And why hasn't the IOC done a tribute long ago about the Munich murders? I have no clue why'd they be against it.
In the 1996 Olympics in Atlanta, American gymnast Amy Chow had planned a floor exercise as a "tribute to the South" with music that featured the tune "Dixie." Someone (not an official) complained that this was a bad song because of its association with the Confederacy, so Chow and her coach had to change it.
(As it turned out, it didn't matter because Chow did not compete on floor anyway.)
