Verse 1: Keyboard plays F#, G#, A# up and down, but the chords are:
B G#m D#m G#m C#m7
I fell asleep on a late night train
B G#m D#m G#m C#m7
I missed my stop and I went round again

Why would I want to see you now?
B G#m D#m G#m C#m7
To fix it up, make it up somehow
Chorus:
F# D#m E F# D#m E
Ba by I'll try again, try again
F# D#m E F# D#m E
Ba by I die every night, every time
Verse 2:
B G#m D#m G#m C#m7
What I was isn't what I am
B G#m D#m G#m C#m7
I'd change back but I don't know if I can

Lay down your arms and I will lay down mine

Rip back the time that we've been wasting

You'd pick me up and you'd sort me out
