At school we sung:

At break of day, I watched the homing swallow,
as towards the south he wings his distant flight,
Oh happy flight.
Thou beauteous bird Ah wish that I could follow,
to that far land, where dwells my hearts delight.

Verse
For ah to thee, my restless thoughts come thronging,
of lovers meeting and the memory of bliss,
both night and day my heart is filled with longing,
again to feel the magic of your kiss.

    There may have been another verse but after 50 years thememory dims but never that haunting melody
