Grass roots movement / improvise

Hey

Take the train when you go, baby
I'll be by your side
Take the train when you go, baby
In the neon night

Train of thought was interrupted
By a thunder's strike
The storm rolls in
I hope you're ready
Look you in the eyes

I'll play the piano for you friend
But I don't know any songs
You can sing one if you want
But don't ask me to play along
It would be nothing but the mashing of keys
With no regard for melody
But if you want me to improvise
Well then
I can improvise
