Was the poem you heard something like this?
Come, O Holy Spirit, come! From Your bright and blissful Home Rays of healing light impart. Come, Father of the poor, Source of gifts that will endure Light of ev’ry human heart.
You of all consolers best, Of the soul most kindly Guest, Quick’ning courage do bestow.
In hard labor You are rest, In the heat You refresh best, And solace give in our woe.
O most blessed Light divine, Let Your radiance in us shine, And our inmost being fill.
Nothing good by man is thought, Nothing right by him is wrought, When he spurns Your gracious Will.
Cleanse our souls from sinful stain, Lave our dryness with Your rain, Heal our wounds and mend our way.
Bend the stubborn heart and will, Melt the frozen, warm the chill, Guide the steps that go astray.
On the faithful who in You, Trust with childlike piety, Deign Your sevenfold gift to send.
Give them virtue’s rich increase, Saving grace to die in peace, Give them joys that never end. Amen. Alleluia.
If so, that’s the sequence for Pentecost. You can read more about it here:

If the OP lives in Canada, this is the sequence he/she would have heard yesterday:
Holy Spirit, Lord divine,
Come from heights of heav’n and shine,
Come with blessed radiance bright.
Come, O Father of the poor,
Come, whose treasured gifts ensure,
Come, our heart’s unfailing light.
Of consolers, wisest, best,
And our soul’s most welcome guest,
Sweet refreshment, sweet repose.
In our labour, rest most sweet,
Pleasant coolness in the heat,
Consolation in our woes.
Light most blessed, shine with grace
In our heart’s most secret place,
Fill your faithful through and through.
Left without your presence here,
Life itself would disappear,
Nothing thrives apart from you!
Cleanse our soiled hearts of sin,
Arid souls refresh within,
Wounded lives to health restore.
On the faithful who are true
And profess their faith in you,
In your sev’nfold gift descend!
Bend the stubborn heart and will,
Melt the frozen, warm the chill,
Guide the wayward home once more!
Give us virtue’s sure reward,
Give us your salvation, Lord,
Give us joys that never end!
