The cast of Bongga Ka, ‘Day! The Annie Batungbakal Musical is shaping up to be truly ‘bongga’, kicking with an all-star lineup of today’s most sought-after theater heartthrobs: Sam Concepcion, KD Estrada, Jeff Moses and Anthony Rosaldo.

Concepcion takes on the role of Romer, a 27 year-old cosmopolitan, flirty, and self-assured man who knows he’s handsome and worldly. He is a flight attendant who dabbles in photography. Coming from a well-off family, he is the only son of the owner of House of Pasion.

Concepcion is one of Philippine entertainment’s most accomplished triple threats. Equally at home on the concert stage, television screen, and theater stage, Concepcion has built a remarkable career spanning over two decades. Theater audiences most recently saw him as the wealthy aristocrat Daniel Beauxhomme in 9 Works Theatrical’s staging of “Once on This Island,” following his widely praised performance as Popoy in PETA’s blockbuster hit “One More Chance The Musical.”

Estrada steps into the character of Burn, a down-to-earth folk-rock singer in his mid 20s. Burn is known for performing cover songs but dreams of making a name for himself through his own original music. Determined to get his big break, he sets out on a journey to achieve his dreams while balancing stability and his passion.

Estrada, whose growing theater career continues to excite audiences, comes fresh off a highly celebrated run of “Bagets The Musical,” where he starred as the well-off, conyo high schooler Arnel. He made his musical theater debut in 2023 in PETA’s award-winning zarzuela-comedy “Walang Aray.”

Alternating as Romer are Jeff Moses and Anthony Rosaldo.

Moses continues to build momentum as one of the most promising young performers transitioning from television to theater. Best known to many viewers through his appearances in hit television dramas, Moses successfully made his stage debut in “Bagets The Musical,” where he portrayed the martial arts-loving Topee. His natural charm and strong vocals quickly endeared him to audiences, making him a welcome addition to the world of “Bongga Ka, ’Day!: The Annie Batungbakal Musical.”


Rosaldo, a powerhouse vocalist and former “The Clash” finalist, has become a familiar face in musical theater through a string of standout performances. In 2024, he starred as Roger Davis in the Manila revival of Jonathan Larson’s “Rent.” Before that, he made his theatrical debut as Young Hector in the long-running hit musical “Ang Huling El Bimbo” in 2023.

Together, these four performers bring a wealth of experience, charisma, and musicality to the production. With its leading men now unveiled, anticipation continues to build for what promises to be a bongga theatrical experience. More cast members will be revealed soon.
