That's how you and I will be

I had never heard this song, until a couple of weeks ago. 

This is odd, considering that I'm familiar with Billy Joel, and have been a fan of the King's Singers for some time. 

 Looking up the song, I find that it's on the last original album Joel released, and the year was 1993. That explains a lot; I had a one-year-old daughter, and wasn't spending that much time listening to the radio. 

Apparently, Joel began this as a prelude to another song in the style of a Gregorian Chant, before turning it into a tribute to his own young daughter. 

The arrangement here, by Philip Lawson, was created especially for an earlier incarnation of the King's Singer nearly twenty years ago. The current members are singing here, carefully distanced from Voces8, another a cappella British group, founded in 2003, about the same time the King's Singers first began singing this song.

Goodnight my angel, time to close your eyes 

And save these questions for another day 

I think I know what you've been asking me 

I think you know what I've been trying to say 

I promised I would never leave you 

Then you should always know 

Wherever you may go, no matter where you are 

I never will be far away 

Goodnight my angel, now it's time to sleep 

And still so many things I want to say 

Remember all the songs you sang for me 

When we went sailing on an emerald bay 

And like a boat out on the ocean I'm rocking you to sleep 

The water's dark and deep, inside this ancient heart 

You'll always be a part of me 

Goodnight my angel, now it's time to dream 

And dream how wonderful your life will be 

Someday your child may cry, and if you sing this lullaby 

Then in your heart there will always be a part of me 

Someday we'll all be gone 

But lullabies go on and on 

They never die 

That's how you and I will be
