I came up with the idea of all 9 girls doing that song together and actually mentioned it in another forum. Here's how i would write it.
I combined ABBA's lyrics with Faryl Smith's lyrics.
(Opening with Mairead on Violin)
(Chloe)
You and I can share the silence
Finding comfort together
The way old friends do
(Lisa)
I always turn to you for guidence
We stand up for each other
The way old friends do
(Hayley)
Time of joy and times of sorrow
We will always see it through
(Lynn)
Oh I don't care what comes tomorrow
We can face it together
The way old friends do
(Orla)
You and I can share the silence
Finding comfort together
The way old friends do
(Deirdre)
And after fights and words of violence
We make up with each other
The way old friends do
(Meav)
Times of joy and times of sorrow
We will always see it through
(Alex)
Oh I don't care what comes tomorrow
We can face it together
The way old friends do
(Mairead on Violin to the Tune)
We can face it together
The way old friends do
(All 8 Vocalists with Choir and Mairead on Violin)
Times of joy and times of sorrow
We will always see it through
Oh I don't care what comes tomorrow
We can face it together
The way old friends do
(All 9 Girls Singing in Unison [Even Mairead])
We can face it together
The way old friends do
(The Girls Close with a Group Hug)
I think that would sound beautiful. I would seriously CRY MY EYES OUT if they did that together.
