What's That Sound Lyrics

I met this guy the other day
He wasn't tall nor short
Just something inbetween
He started talking
Asked for a street
I did not know
The sound of his voice
Not light not dark not high or low
It still rings in my head
Hey hey what's that sound?

He said goodbye
I said it too
He started walking
I did too

The sound of his voice
not light not dark not high or low

It still rings in my head
Hey hey what's that sound?
