A few weeks ago, I discovered that Komm Gib Mir Deine Hand has an extra guitar overdubbed.
The guitar I'm talking about makes the ascending scale after the words (in German, of course!) "Oh Yeah I'll tell you something... (GUITAR) I think you'll understand".
That guitar is not present in any of the other mixes of the song: Mono, Stereo, Anthology, Love, Rock Band. Maybe because that overdub only exists in the German multitrack.
Probably when they were recording the german vocals they noticed that that particular guitar riff was a little weak and tried to reinforce it.
And finally, I think the reason nobody noticed this thing is because nobody EVER listens to that track!
