I came across this video and it made my day. It also made me cry. Sometimes the most beautiful moments in life come to us as small surprises. Here is the description:
Last month at the central market in Valencia, Spain, opera singers disguised as shopkeepers were selling produce at the various stalls.
Suddenly, Verdi's La Traviata starts playing over the loudspeakers and they burst into song. None of the shoppers had a clue what was going on. Sort of like candid camera, but completely charming....ENJOY!
