At work, they are Senior officers at the Economic Development Board (EDB).

Outside work, they are members of Ricochet, an all-girl group that performs catchy pop tunes and slick dance routines à la Korean group Girls’ Generation.

Impressing the judges during auditions, Tiffany Ong, Zabrina Chew and Isabelle Techawatanasuk clinched a spot on Sing A Nation, a televised group singing competition which airs in July.

The show’s producers grouped them with three other female contestants for greater stage presence.

All Sing A Nation participants will join this year’s National Day Parade (NDP) choir, with the winning group being the centrepiece. Participants will also share their experiences in being part of the nationwide celebration on the NDP website.

After seeing the TV promos, Tiffany, 25, who works in Human Resources (Talent Management), decided to form a group to join the competition.

So she roped in Isabelle, 21, from Professional Services and Zabrina, 23, from the Global-Asia Programme Office, both of whom are musicians.

Preparing for the competition on top of other commitments in their lives hasn’t been easy. Zabrina recalls how she practised by watching videos of her group’s choreography sessions while on holiday. “When I arrived in Singapore (on the competition day), I had to jump straight into the whole thing and be ready to perform. It was crazy!”
