“We both heard a mistake somewhere in the end of the song. We listened again. Couldn’t find it. We searched a bit, then moved on. We’ll find it. ……Then, next day we had a playback with people there. We heard it again. It’s in the third verse. Later in the studio we located it and there didn’t seem to be a problem. It sounded fine. That happened a lot with this record. Ghosts are in the grooves.”
