  4. Sing along

    Soprano Laura Wright is doing the honours with the traditional pre-FA Cup (and now pre-5liveaside) song Abide With Me.

    We hope you're standing and singing along!

    Here are the lyrics to help:

    "Abide with me, fast falls the eventideThe darkness deepens, Lord, with me abideWhen other helpers fail and comforts fleeHelp of the helpless, O abide with me

    "Hold Thou Thy cross before my closing eyesShine through the gloom and point me to the skiesHeavens morning breaks, and earths vain shadows fleeIn life, in death, O Lord, abide with meIn life, in death, O Lord, abide with me"
