I first heard the "Spanish Lady" from the lips of Wilfried Drygala in Idle Fellows
and I believe he got it from a The Dubliners
recording. He used to sing it beautifully. The song is of a young man on the spree in Dublin who becomes enamoured with a "Spanish Lady", probably a euphemism for a lady of doubtful character, but is unable to consummate his desires. The meeting is of such consequence that he remembers her for the rest of his life. Even in old-age, our hero wonders where she might be.
The song may be found in 100 Irish Ballads Volume 1
