BR: 2-07 The Finest in the Land

I read The Finest in the Land.
To celebrate Kipper's birthday, Annene and her friends form a band. When they began to play Happy Birthday, the magic key began to glow. The magic took the children back in time. There were many entertainers, but their performances were so bad. Entertainers thought, the children were musicians. Suddenly, man came. He needed musicians, and took the children to castle. Then entertainers performed in front of the king. The entertainers were terrible. Everyone began to shout and throw food at them. The king was angry. Next children played Happy Birthday. He prased them. Then they backed in their home. There was Kipper's birthday party. They needn't practice to play Happy Birthday.
I wonder why entertainer's performance was so terrible. They were pity. I wanted them to cheer up.
