To the powers that be I would personally be very eager to purchase a dc-music or soundslice or Horowitz book on the following topics.
1. Intros, outros and interludes
2. Lead guitarist playing behind a violin or clarinet.
Putting a bug in people's ears for anyone who wants to produce some lessons :o)

I don't know if you've seen some of this content, but Robin Nolan's Gypsy Jazz Transfusion does monthly deep dives into a song. They cover all sorts of topics, including intros and outros. It is a monthly fee but you can cancel any time you'd like. You can probably find examples for free on youtube, but these would be intros that could be adapted to any song.
As for your request re: playing behind clarinet, I thought of these 3 videos Yaakov Hoter did with Evan Christopher. Here's the first one linked. Its been a while since I've listened to them, but maybe they have something you seek? Otherwise, I'd say try to get to Django in June. I'm certain some of the instructors could help you there...and you get to eat, breathe, sleep Django for a whole week.
Rino goes through some of that in his Soundslice course: https://www.soundslice.com/store/django-style-fills/
That is exactly what I wanted. Thanks!
