Here you are, Joe - from your description it has to be this one you heard yesterday! (Someone beat me to singing it cos i was further back in the queue!)

Singing In The May (Mike O’Connor)


The street was hushed, the listening stars were bright,
The church clock chimed at twelve o’clock midnight,
And as its echoes died, voices at my side
In unison replied: “Unite, unite”.

Refrain:
Singing in the May, Singing in the May,
(Repeat last line of verse, eg:)
In unison replied: “Unite, unite”.


I heard familiar voices in the crowd,
Soft but clear this song they sang aloud;
From many miles away, old friends seemed to say:
“Let all upon this day unite, unite”.


Then voices we had thought to hear no more
From generations that had gone before
With us seemed to sing, these words re-echoing:
“As Summer follows Spring – unite, unite.”


And from the narrow streets came this reply,
Across the harbour to the starlit sky,
As children yet unborn sang in the new May morn,
To welcome Summer’s dawn – unite, unite.


And from the town the rising voices cried
That all should be as one, whate’er betide;
Now Winter-time has gone, the wheel of life rolls on,
For Summer is a’come – unite, unite.
