Since the only information we have is from the title, Knapp could be anyone. He might be a fictional character created by the author to tell a story about how drinking and love intersect. It's possible that he's a complex character with many facets to his personality, which will be revealed as the story progresses if we had more of the story to read.
Caroline Knapp is the author of this work. She is likely sharing her own experiences related to drinking in the context of what she describes as a 'love story'.
I'm not sure specifically as the title is rather unique. It could potentially be a story where the act of drinking by a character named Knapp is intertwined with a love story. Maybe Knapp has some drinking experiences that are related to his love life, like meeting his love interest in a bar or having some deep conversations over drinks.
The main theme is likely about the complex relationship between drinking and what could be considered a form of love, perhaps an obsessive or self - destructive kind of love related to alcohol.
George in the George and the dragon story is a knight. He is a brave and heroic figure who is willing to face the dangerous dragon to protect the village.
I'm not sure who George McKenna specifically is in 'the george mckenna story' without more context. It could be about an individual with unique experiences, achievements or a particular journey.
George McKenna might be a person with a remarkable life journey. He could be a figure who has made significant contributions in a particular field. It could be in the areas of civil rights, where he fought for the rights of a certain group. Or perhaps he was an entrepreneur who started from humble beginnings and built something great, and the story is about his rise to success and the challenges he faced along the way.
As mentioned before, without more context, it's hard to determine who this George Ty is. He could be an entrepreneur, an artist, or someone in the academic world.
