Drumming on a Chair

From "The Beatles Recording Sessions," 3 September 1968:

Brian Gibson recalls one Beatles session where overuse of the
eight-track facility resulted in an extraordinary overdub. "There was
one song, I can't remember the title, in which they'd added so many
instruments that you couldn't hear the drums any more. So they
overdubbed Ringo playing a chair, a red plastic Abbey Road chair,
slapping the drum sticks on the cushion and making a thwack to emphasize
the snare beat, because they'd buried it."

Adam...

Thank you, everyone, for your thoughtful answers. I listened to all my
Beatles CDs again (some chore, eh?) and *my* vote for drumming on a
chair has to go to "I'll Follow the Sun," even though it was long before
the days of eight-track recording. The "drumming" on that song
certainly sounds like a chair cushion to me, anyway. What do you think?

Adam...

P.S. Since writing the above, I've read Geoff Emerick's book. He was
2nd engineer at the recording of "I'll Follow the Sun," and says that
the "drum" sound was Ringo slapping his own legs.

Does anybody know, or have a good guess, at which song this is?

Anderz...

Yeah, t´was Because of course.
