"James Connolly" by Larry Kirwan of NY Irish band "Black 47" is also interesting. It's on "Fire of Freedom" album, EMI, 1993.
Two of Connolly's own lyrics, "A Rebel Song" and "Watchword of Labour" are included on the album "Songs of Irish Labour", 1998, produced by Dr Helena Sheehan of Dublin City University.
