One fairly useless thing that didn't really occur to me until today: Very few of the same celebrities appear in both this set and the 40th anniversary collection.
The only celebrities in both are Madeline Kahn, Patti LeBelle, and Feist - with Feist being the only one whose same segment is in both (she's the only one of them to only appear in one segment on the show in total).
Most of the celebrity appearances are in clips from the last ten years (after the 40th anniversary came out), and most of the clips from the 2010's are celebrity appearances - Amy Poehler, Josh Groban, Thomas Rhett, Solange, Janelle Morre, Will.I.Am, and the woman who sang "Just Like Magic"... seven out of ten.
