Definition: "Yes, and" is a rule-of-thumb in improvisational comedy that suggests that a participant in a dialogue should accept what another participant has stated ("Yes") and then expand on that line of thought or context ("and..."). Given a prompt and two responses, identify which response is the type of "yes, and". Indicate your answer by 'Response 1' if the first response is correct, otherwise 'Response 2'.  Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange.
Input: Prompt: You don't think he's given up on jazz, do you? 
 Response 1: I'm a ghost writer. Murray was too shy to write his own book. So, he employed me to stand in and experience his life with him as he told me stories of his past. 
 Response 2: Trumpet Davis, the legendary Jazz guy? I don't know if he ever could.
