How to instruct to respond with mix of provided content and "OpenAI" content?

I am trying to create a prompt that asks completions to extract people from provided content and then use OpenAI model (35-turbo) to provide a short bio but cannot seem to get the system role to instruct correctly.

Essentiall find “Taylor Swift” in the content provided and then use the model to provide a bio for “Taylor Swift” like “TS is a singer…” etc.

I cannot seem to get it to use the content provided AND not the content. Has anyone had a good prompt for doing this to use provided content for parts of the answer and the full model for other parts?

Thx for the help.
