It's definitely one of the things which did it for me, too. For a few reasons, I actually went 15 years without listening to virtually anything I'd listened to in high school or college—I mean, I literally didn't listen to an entire Who or Stones or Zeppelin or, yes, Floyd song for a decade and a half. And when you take a break that long, hokey smokes does "Free Bird" or "Stairway to Heaven" or "Sympathy for the Devil" or "Won't Get Fooled Again" or pretty much the entire Pink Floyd oeuvre hit like a ton of bricks.
And I really appreciated just how well Nick Mason played for the song. Sure, he had nowhere near the chops of a Bruford or Collins or Palmer but damn the guy had a style and he had musicality and he had restraint. And he changed over the years--his playing on Animals or The Wall sounds virtually nothing like his playing on Atom Heart Mother or Meddle, and yet it all still feels like him.
