Well, reading the criteria,
1)
famous songs that were
recorded
2) using Guild
acoustic guitars,
a Bluesbird or Starfire for instance wouldn't count!
But it's very difficult to proof what was used during recording, so maybe we should say finding a Youtube video of an acoustic Guild in "famous" songs is better.
"Famous" means people around the world would recognize it. (not only people in the US).
But even that task is very tough...
So lets see what I found. There were good names mentioned already.
I just list whatever I remember playing Guild acoustics without researching if the song was written by them or recorded with the Guild, it's a fun list I think.
Paul Simon (F-30R) (Those songs are probably known really all around the world!)

Sorry, it got a bit out of control as it looks...I veered away from the original posters request...but at least stayed with the acoustic guitar request.
