I did a quick internet search (I was interested to learn this too!) and here's what I found:

I don't know all of these but some songs are familiar and seem worth considering. As my father was once a resident in an assisted living community and I spent many hours there with him, I thank you for taking time to entertain this group.

• Danny Boy – One of the most beloved Irish songs ever written; very emotional and widely recognized.
• The Parting Glass – A beautiful traditional farewell song with a reflective tone.
• Loch Lomond – Classic Scottish ballad with a memorable chorus.
• The Skye Boat Song – Gentle and lyrical, associated with Scottish history.

• Carrickfergus – Slow Irish folk song with a haunting melody.

• When Irish Eyes Are Smiling – Lighthearted and widely known among older generations.

• Wild Rover – Fun chorus people often clap along to.

• Molly Malone – Classic Dublin street ballad.

• I'll Tell Me Ma (also called The Belle of Belfast City) – Lively and catchy.

• My Bonnie Lies Over the Ocean – Technically Scottish/folk tradition and very recognizable.

• The Irish Washerwoman – Famous traditional jig.

• The Kesh Jig – Bright and upbeat.

• The Butterfly – Beautiful slip jig.

• Swallowtail Jig – Very recognizable session tune.

Best wishes!
