The article referred to was written as a pamphlet by one James Tully and was the basis of Yeats' The Last Gleeman essay. It includes the following:

St. Patrick was a Gentleman
Zozimus's Great Recitation (The life of Saint Mary of Egypt) (poem)
Maguire's Triumph (poem?)
Finding of Moses (two versions)
Dickey and the Yeoman
The song of Zozimus
A new song on the two corporations
The address of Zozimus to his friends
The Grand Song of Zozimus on the Liberty (Ye men of sweet Liberty's hall)
Song on a trial of Daniel O'Connell (no title)
The T.B.C. (air: Shan van Bocht)


As you say, Zimmerman's great Irish Songs of Rebellion ascribes Dickey in the Yeomen and Billy's Downfall to Zoz, though taking the words from broadsides.

Regards.

p.s. The exagerated Dublinese usually heard when Moses is sung, seems to have been introduced when it was published in the Cuala Press Broadsides edition in the 1930's.
