I didn't see the Grammy performance you talk about, but the part you describe does sound funny. I don't know about latin, but I do know of a singer-songwriter (Chris Judge smith) who wrote an entire opera in Esperanto
! (Do you know what that is?) Now that would be interesting to hear!
I think the film you mention is called 'Phonebooth' in English. Is it the film where a sniper pins down a man in a phone booth in New York. If it is, then I agree with you - I was gripped to my seat
all of the time. Incredible!
