The fourth.

"The dock of ..."was written by Otis Redding. I didn't know who he was. So, I tried to
reseach on him on the internet. And then, I knew a terrible fact that he was died by accident in 1967. According to his biography, he was born in Geogia in 1940's. He was really big in 60's. I think he was the great R&B singer. I love his soft, soulful, and a little husky voice.
