I saw this guy while eating dinner with the VietnamWorks Tech Team in Vung Tau in April. He and his buddy were traveling from restaurant to restaurant singing romantic songs and selling trinkets. His enthusiasm and passion were contagious. I got the feeling that he didn't care a whit if they sold anything, he was just thrilled to have an audience.
Another reason I like this pic is because it shows well the Vietnamese love affair with massive, over-the-top audio amplification.
