Liam Clancy sings a beautiful version of Aghadoe, with Images.
By poet and composer John Todhunter, it's unknown if the event described in the lyric was based on any real-life story. It’s a ballad about the Irish Rebellion of 1798, narrated by a bereaved female, about her rebel lover, hidden, betrayed, and executed

There's a glen in Aghadoe, Aghadoe, Aghadoe
There's a deep and secret glen in Aghadoe
Where we met my love and I, love's fair planet in the sky
In that deep and silent glen in Aghadoe

There's a glen in Aghadoe, Aghadoe, Aghadoe
There's a deep and secret glade in Aghadoe
Where I hid from the eyes of the redcoats and their spies
That year the trouble came to Aghadoe

But they tracked me to that glen in Aghadoe, Aghadoe
When the price was on his head in Aghadoe
O'er the mountain through the wood as I stole to him with food
But the bullets found his heart in Aghadoe

I walked from Mallow town to Aghadoe, Aghadoe
I took his head from the jail gate to Aghadoe
There I covered him with fern and I piled on him the cairn
Like an Irish king, he sleeps in Aghadoe
