The SingStar audio/video is 3:56 long, so it's very close to the official video, but indeed differs in lyrics/timing towards the end. I adapted it so it should work better now with the video below.
Towards the end this doesn't match the video at all. It's more than just removing a sentence and moving everything after it to start at beat ~3276. The pitch is also off after that, and there's several notes that aren't that long at all. That was the point where I gave up trying to fix it.
I'm going to take a guess that the SingStar version is a different version entirely, but as is customary for SingStar its video quality is atrocious, so I'd like to upgrade to this one.
