Specify the name of a music band

So this old man is walking down the street in Brooklyn.

He sees a young boy sitting on the street in front of a candy shop, shoving sweets in his mouth as fast as possible.

The man walks up to the boy and says "You know son, it's really not healthy to eat all that candy."

The kid looks up at him and says, "You know my grandfather lived to be 97 years old."

The man replies "Oh and did he eat a lot of candy?" The kid looks at him and says "No, but he minded his own fucking business."
