Fairport Convention - Book Song lyrics

If she knew what I've seen while I'm watching Would she know where to smile, what to say? When she leaves from her book to be with me Where's her mind as she stands while I play? She left behind names in the pages And the time she took out, they stayed in Now she thinks that she maybe should tell them Of my book and the places she's been Now she's looking at me while I'm writing Does she know where to smile, what to say? When she leaves from her book to be with me What's she thinking about while I play?
