"Yes It Is" guitar swells... how many tracks? | Fab forum

I love this track. And the guitar swells make it even better. Gives it character that is unique. I like them more than the decent swells on "Wait"

But it seems to me that there are two players (or tracks/layers) of fills. you can hear that sometimes there are two guitar sounds swelling at completely different registers of the instrument that would be difficult to play at the same time (or harmonics ringing while other swells are still in). And some start while others haven't died yet. Were there two different tracks of guitar added, or two players doing fills? And, did John ever help George with the swells by toggling the volume on any tracks or is this all a foot pedal that George is using?
