Mole is a terrific musician but the problem is, he gets stage fright and can’t play in front of a crowd.  At a school talent show, he doesn’t want to play because of fear, but comes to the rescue of his friend, Pig, whose iPod broke and needs some music for his dance.  Mole overcomes his fear.  The references of Mick Jagger and Bruce Springsteen will go over young readers’ heads, but the adult reader will know who is being referred to.  Okay, but not necessary.
