A young boy returned from his first music lesson on the bass. "How did it go?" asked his father.
"Great," said the boy. "I learned how to play a 'C'."
The next week the boy took another lesson and his father asked about the lesson.
"Terrific," said the boy. "I learned how to play a 'G'."
The following week the boy did not come home. The father was frantic when the boy finally came home it was after 2:00 AM.
"Where in the world have you been?" screamed the father.
"I had a gig," answered the son
