 2020 Annual Gathering:  CANCELLED      

The officers and council of the O Mahony Society have made the difficult but responsible decision to cancel the 2020 Gathering due to the corona virus pandemic.

Continuing an Irish tradition:              Bring Your Party Piece!

by Mary McConnell Haislip, Membership Coordinator

This longstanding Irish tradition isn’t well known in many parts of the United States.  My mother, whose grandparents were from Ireland, used to tell of family parties and about everyone’s "Party Piece."  She remembered details about each one.

So what is it?  Very simply, a way of sharing our talents and laughter with one another.  Everyone comes prepared with something to entertain:  a song, poem, dance, joke or impersonation, magic trick, musical instrument, etc. etc.  It’s part of the social fabric of family gatherings, so for this year’s Gathering bring your Party Piece, because we are going to be the entertainment! 

We’ve done this in years past, and were accompanied by and entertained by the late Canice O Mahony’s mouth harp and his wife Eilish's spoons for several years.  I remember my first O Mahony gathering in 2001; my sisters and I weren’t prepared for a "Party Piece."  But we were given the mic anyway, and the only song we could remember all the lyrics to was America the Beautiful.  Boy, did we feel silly! 

Making your own party by singing and laughing together is a marvelous, entertaining way to spend the evening.  You really get to know everyone better, and share a lot of fun.  So what will your Party Piece be for 2020?
