Tom Petty tribute but no Kirwan or Welch?

[Macfan4life]

I'm confused so please help me out. I know there is a Tom Petty tribute during the Mac's encore with several photos of Stevie and Tom together ending with a huge photo of Tom Petty on the screen behind the band.
Tom Petty passed away in 2017. Danny Kirwan passed away only a few months ago and its wonderful Christine is singing one of his songs. Are there any photos of Danny on the screen? A small tribute? Any videos playing of Danny performing with the Mac? The same goes for Bob Welch. Any sign of him or tribute?
I have not seen the concert but I am curious. It seems odd to me that Petty gets such a tribute but not the Fleetwood Mac members.
