In collaboration Bay Chamber Concerts and PORTopera, Helen and Bob Blakelock of Damariscotta Mills will explore “La Fille du Regiment (The Daughter of the Regiment),” PORTopera’s July festival opera during an illustrated program Sunday, June 12 from 3 to 5 p.m. in the recital hall of Bay Chamber Community School, 18 Central Ave.

Music, history, biography, quantum leaps into supposition, gossip and trivia will keep the afternoon lively, lighthearted and informative. Helen provides the commentary and Bob creates the audio/visual excerpts geared to entertain while previewing the opera and energizing the potential opera audience.

The Blakelocks have given opera programs at New England College in New Hampshire for many years. Prior to that, Helen was a popular presenter at pre-opera luncheons and dinners for the Opera Company of Boston. She has been the featured speaker for Opera Guilds International, Boston Women’s Council, Belmont Woman’s Club and other civic and cultural organizations.

Founding President Jack Riddle, nationally recognized for his work on behalf of PORTopera, will provide an overview of the many activities and facets of PORTopera’s offerings. Warren Schubert, member of the board of both Bay Chamber and PORTopera, will make the introductions.

Light refreshments will be served, and some lucky attendee will win two tickets to the July 30 performance of “La Fille.” For more information about this free, public presentation, call Schubert at 236-6126.

Opera tickets are on sale now for “La Fille du Regiment,” July 28 and 30 at 7:30 p.m. at the Merrill Auditorium in Portland. For more information, call 842-0800 or visit portopera.org.
