I’ve got one idea, that uses the end credits version of “Parade of the Ewoks” (appropriately upbeat/triumphant for the party - and has Yub Nub vibes sans lyrics), that segues into “Luke and Leia” from the end credits once Luke shows up.
I really dislike “Yub Nub” and “500 Nations Ripoff,” so finding something from the 1983 OST that “works” is my goal.
