The Philadelphia Opera Company staged an event at a huge Macy's dept. store. They were dressed as shoppers and suddenly burst into a beautiful rendition of Handel's Messiah. It is at first humorous to see the reaction of the shoppers as they are astonished by the outburst of their fellow "shoppers". Watch this:
What a contrast between the commercial aspect that Christmas has become and the true meaning found in this beautiful music. The power and majesty of the music says it all.
