Abiding with all of Abide with me

Did you realise that Abide with me has some 'extra' verses (in bold below)?
I guess if you did know these then you wouldn't think they were 'extra'!! In any case they were extra to me when I stumbled on them recently.
Why don't we sing them?
I expect there is the practical reason, that 8 verses is long by today's standards. I wonder too if these verses are not just too robust in talk of sin and judgement, not to mention Christ centred for most funeral settings (let alone the FA Cup Final!!)?
But aren't they wonderful? And not just for funerals.

Abide with me; fast falls the eventide;
The darkness deepens; Lord with me abide.
When other helpers fail and comforts flee,
Help of the helpless, O abide with me.

Swift to its close ebbs out life’s little day;
Earth’s joys grow dim; its glories pass away;
Change and decay in all around I see;
O Thou who changest not, abide with me.

Not a brief glance I beg, a passing word;
But as Thou dwell’st with Thy disciples, Lord,
Familiar, condescending, patient, free.
Come not to sojourn, but abide with me.

Come not in terrors, as the King of kings,
But kind and good, with healing in Thy wings,
Tears for all woes, a heart for every plea—
Come, Friend of sinners, and thus bide with me.

Thou on my head in early youth didst smile;
And, though rebellious and perverse meanwhile,
Thou hast not left me, oft as I left Thee,
On to the close, O Lord, abide with me.

I need Thy presence every passing hour.
What but Thy grace can foil the tempter’s power?
Who, like Thyself, my guide and stay can be?
Through cloud and sunshine, Lord, abide with me.

I fear no foe, with Thee at hand to bless;
Ills have no weight, and tears no bitterness.
Where is death’s sting? Where, grave, thy victory?
I triumph still, if Thou abide with me.

Hold Thou Thy cross before my closing eyes;
Shine through the gloom and point me to the skies.
Heaven’s morning breaks, and earth’s vain shadows flee;
In life, in death, O Lord, abide with me.

Henry F Lyte, 1847
