[3] She appeared in Julius Benedict's opera, The Lily of Killarney at Dublin's Olympia Theatre in 1960, alongside Veronica Dunne, John Carolan and Denis Noble with conductor Fr.
However, Greevy never developed the acting skills necessary for true operatic success, and made her musical mark instead in the world of oratorio and song recitals.
She was introduced to works such as Elgar's The Dream of Gerontius and Handel's Messiah by Sir John Barbirolli, and later recorded music by Mahler, Bach and Haydn.

The Times praised the 26-year-old Greevy's "full, glowing voice, rich and firm at the bottom, radiant at the top, and gloriously expressive phrasing".
