Who's missing?

[Tref]

Apparently, Lindsey Buckingham was the only one not actually given a line to sing. I bet it was kind of awkward as they were calling all the names to come up & collect their lyric sheets and poor Lindsey remained by himself. I imagine he just said, Hey, no biggie, I didn't feel like singing anyway, but deep inside he was thinking, This is bullsh-t, I was in Fleetwood F'in Mac!
