Since the MIDI download button didn't download anything (ad blockers?), I recreated Google's on-screen notation with the "MidiEditor" application by Markus Schwenk. SATB voices have been distributed to the I+II+II+P channels/divisions, playback speed in HW was set to 33.4% for a reason. ;)
"Original" (== MidiEditor) MIDI file has been attached, so it does not depend on a particular sample set. Please feel free to play around with it as you like.
