A Flute Expert Grandfather

This unfortunate fate befell my grandfather to seek sustenance to provide for his family. This grandfather visits the coffee shop every day to sing with his bamboo flute, if someone gives him a little change he is very happy, besides he sings he also offers massage services. When he approached me, I asked him to sing with a flute a song for me to share on @dtube in hopes of getting a lot of upvote that I would give to this grandfather. thank you
