In the hope that this extra little bit may jolt someone's memory, I include all the lyrics I can find. The two mentions of Joyce, I cannot explain. I am not even sure if the two verses are from the same song or two different songs. Anyay, if anyone can add anything further, it would be appreciateed.
Again, any Horslips fans out there? One of you should have this!!

In early spring when small birds sing and lambkins sport and play,
My way I took, my friends forsook, and came to Dublin quay;
I enter'd as a passenger, and to England I sailed o'er;
I bade farewell to all my friends, and I left the shamrock shore. (Joyce, 1890)

Ye muses mine, with me combine and grant me your relief,
While here alone I sigh and moan, I'm overwhelmed with grief:
While here alone I sigh and moan far from my friends and home;
My troubled mind no rest can find since I left the Shamrock shore. (Joyce, 1909)
