For the Peter Gabriel song "Sledgehammer", all the lyrics sites list the first two lines of the song as being:
you could have a steam train
if you'd just lay down your tracks
But every time I hear the song, it's evident that he sings something before this. It sounds a bit like "Someday... you don't want to lose it..." and then goes into the steam train line.
However it's indistinct and I've never been able to make out the words.
You can also see this in the music video - there are clearly words said/sung before that steam train line. Again, they are indistinct.
No lyrics site I've found lists those first words. Is there anything that tells us what they are? Can someone who can lip-read look at the music video and decipher them?
