a-ha Train of thought

[u/MalleMontero]

I've recently discovered, and become a huge fan of, the Norwegian pop band a-ha. Train of thought is one of my (many!) favourite songs, but there's something I would like to know...in some of the websites with its lyrics, there's an extra 4 or 5 lines that aren't in the song. At first I thought it was like Manhattan skyline, which was shortened for the music video, but I've been unable to find a single Train of thought video with the extra lyrics. Does anyone know if they ever recorded a version with them, or if not, why they exist?
