Thanks for this thread. I have a St. Patrick's Day gig at, of all places Ye Olde England Inn" I have a feeling I'll be pulling out "Danny Boy" which is a lovely song if done right (there's a reason for the chestnuts) but may not do "Old Mother England." Thread creep, I know.

Colcannon works well (the Black Family does this)
"the Jolly Tinker" If I can do it without getting mortally embarrassed.
"Seven days are In a Week"
If I Was a Blackbird"
"It Was Pleasant and Delightful"
"I know my Love By His Way of Walking" (I've only heard Danny Carnahan do this one)
Do You Love an Apple (depressing, but a great song)

The Clancys did a lovely version of "One Morning in May" Different title, Chorus went

Oh they kissed so sweet and comforting as they clung to each other
They went arm and arm down the road like sister and brother
They went arm and arm down the road 'til they came to a stream
And they both sat down together love to hear the nightingales sing.

If you're feeling adventurous and sober, Mary Mack, Heather on the Moor, Holy Mo Me Father Loves Nikita Kruschev, Anyway, that got me thinking too. Thanks.
