Analysis of A Bygone Occasion (Song)

That night, that night,
That song, that song!
Will such again be evened quite
Through lifetimes long?

No mirth was shown
To outer seers,
But mood to match has not been known
In modern years.

O eyes that smiled,
O lips that lured;
That such would last was one beguiled
To think ensured!

That night, that night,
That song, that song;
O drink to its recalled delight,
Though tears may throng!
