The morse is subtle but if you listen closely you can hear it. Set the Soundcloud player to 1:25 or so and you'll hear singing as they finish up the chorus. As the chorus completes at about 1:31 the singing stops and instruments play. Listen closely, and try to remember what morse sounds like in the movies. It's there in the background, and once you hear it it's obvious. Don't listen to the drums or tambourine, it's not there in the beat. It's "behind" the beat as if a background instrument was playing.
(edit: it also kicks in again around 2:30 and 3:30. So the start times are at approximately 1:30, 2:30, and 3:30.)

I'm a ham operator from the days when Morse was required for all licenses. They really relied on the fact that the captors were not trained (otherwise they would have picked it off, it is obvious if you've spent quality time with a keyer), as well as the captive soldiers were trained to receive at a fairly good speed (it's too fast for me, but it's been years since my last conversation via morse code. Damn internet.)
I thought it was pretty obvious, it plays at a pitch higher than the rest of the chorus and doesn't fit the rhythm. But then again, I was waiting for it.

Outstanding.
