Another Morning Without You was a demo version of what was to become Like An Angel Passing Through My Room. The person making annoying noises is apparently one of the drummers in the studio. (Sorry!)
This recording has previously been reported as 'fake', but to any skilled listener it most certainly is not. If you listen carefully, you can just about make out Angetha and Frida's vocals in various points of the song (most notably, Frida singing 'Without you' towards the end).
