A few weeks late of the Youtube uploads but here are the Instructor Jams and various performances at Lindyfest back in March.
My favorites in no particular order:
Dawn and Frankie: I had mentioned in my post on Lindyfest the impact and delivery that old-timers like Dawn and Frankie have in each simple step and you can see the commitment to it in every step here.
Skidoo and Jam: A solid opening into a jam with members from 23 Skidoo and event instructors. Polished off with a California-like routine at the end.
Here are the rest of the videos as links.
