I don't know if we are allowed to send links to songs, but this song was sung by Steve Green from an arrangement of Handel's Messiah by David Hamilton. I saw it sung from a guy in Chile named Javier Beroiza, using the same soundtrack from Green. I can understand most all of the lyrics except one part partly because the applause was distracting. It was right after "ha resucitado Cristo el Senor..."
Thanks
