My favourite performance (today) is Sham-A-Ling-Dong-Ding by Jesse Winchester.
I love Blind Mary by Turlough O'Carolan -no words, but lovely tune.
I'm So Lonesome I Could Cry has some lovely lyrics

The second half of When You And I Were Young Maggie really appeals to me (perhaps because I'm married to a Maggie)

They say we are feeble with age, Maggie
Our steps are less sprightly than then
Your face is a well written page, Maggie
But time alone was the pen.
They say we are aged and grey, Maggie
As spray by the white breakers flung
But to me you're as fair as you were, Maggie
When you and I were young.
