When was John last Saturdat Night Live episode What year what who the host?

It's tricky to answer definitively without knowing which "John" you're asking about. "Saturday Night Live" has had many Johns as hosts and cast members over the years.

To help me give you the right answer, could you please clarify:

* Which John are you referring to? (e.g., John Mulaney, John Travolta, John Goodman, etc.)

* Do you mean the most recent episode hosted by that John, or are you looking for a specific year?

Once I know this information, I can give you the details you need.
