I find the song Sweet Sixteen goes down well with the old folks as done by the Furey's. Not sure of its origins but they seem to love it.

When first I saw the love light in your eyes
I thought the world held naught but joy for me
And even though we drifted far apart
I never dream but what I dream of thee.

Chorus:
I love you as I've never loved before
Since first I saw you on the village green
Come to me or my dream of love is o'er
I love you as I loved you
When you were sweet,
when you were sweet sixteen.

Last night I dreamt I held your hand in mine
And once again you were my happy bride
I kissed you as I did in Auld Lang Syne
As to the church we wandered side by side

I love you as I never loved before
Sincefirst I met you on the village green
Come to me or my dream of love is O'er
I love you as I loved you,
When you were sweet
When you were sweet sixteen

There may be more to the song than what I've written but that was from memory. Try it out, the old folks I have played it to loved it.
