I was working in GR during the beginning of the Millennium Celebration and we asked that same question and managers told us to say that the song is in no particular language. They wanted to create something that would bring all nations together, therefore, it shouldn´t be in anyone´s language, so everybody could sing it. Now, figure out what the words are! But whatever you sing, it will be good!
LOL! we do have the teletubies! I don´t know much about kids stuff cause I still don´t have them...thank God..... hehe, but I have seen the teletubies! Very popular here!
