As far as I can see, the video is not exactly usable for this case. If you want to use the other audio and this video, then use
#VIDEOGAP:47.6
but it will be out-of-sync after 30 seconds into the song.
I submitted an edit as first rough attempt to fix timings in the song so that it fits the video below. Additionally I had to add some missing lines and deleted several "So" that seem to actually not appear in the song.
