Another Brick In The Wall Pt2

[Hot Tub]

Bit of a strange one. If I listen to this really, really carefully, it seems like there's an octave played on the A and C - it's almost like a ghost note. Anyone else aware of this, or am I hallucinating?

I haven't heard the tune in ages, but I remember whenever it has come up in rehearsals, I've played octaves on a couple of the notes. It just sounds right.
