'Ombra mai fu' from Handel's Xerxes. I don't think what was sung by this choir is the English translation though..... In English: Tender and beautiful fronds of my beloved plane tree, let Fate smile upon you. May thunder, lightning, and storms never disturb your dear peace, nor may you by blowing winds be profaned. Never was a shade of any plant dearer and more lovely, or more sweet.
You can see that the two blokes on the front on the viewers right side next to the girl in the front row were chatting during the first 48 seconds. I could bet he wasn't chatting about how magnificent The Lord God Is. He can be thankful I wasn't the Pastor of the Church there, otherwise I would have kicked him out.
