Cyril and Libbye Hellier

Earlier that year, however, they formally debuted in a production of Puccini's Suor Angelica (with Libbye essaying the name role), at Loyola University of the South.

After a hiatus of seven years, the Helliers returned to the stage for the title roles of Humperdinck's Hänsel und Gretel, for The New Opera Theatre, New Orleans.

In April 1991, the Helliers were soloists in Part III of Handel's Messiah (in the Foundling Hospital Anthem version), at St Francis de Sales Cathedral, Houma.

In recent years, the twins have been heard in the celebrated "Katrina Memorial Concerts," at the Church of Our Lady of Good Counsel, in the Garden District of New Orleans.

Their most recent appearance was at "A Christmas Concert," at St Stephen Church (now a Minor Basilica), in New Orleans, in 2009, at which they performed a duet by Peter Cornelius.
