I think we could argue forever on whether the episode as is would have given Black a legit reason to get paid or cause trouble because IMO once the changes were made to making Vaughn, Joey Collins and giving a different backstory and a different outcome of what happened to Danno, the "Daisies" footage basically became a case of an extended use of stock footage owned by the producers just like the reusing of the tour guide bus spiel in front of the Iolani Palace in more than one episode.

But I do think we can agree that the change from Thad Vaughn to Joey Collins wasn't a case of the producers being stupid, but a case of they knew exactly what they were doing from the get-go and they obviously felt they had sufficiently covered all their bases legally so that if Black did protest, it was going to be a longshot for him to prevail at best.
