Singers Saab Magalona and husband Jim Bacarro released a new song in memory of their baby girl, Luna Isabel, early Friday.

The track, a four-minute nostalgic trip, was written by the parents for their “angel,” who died during childbirth in March last year due to unforeseen pregnancy complications.

“Jim and I wrote parts of this song about 6 years ago. We never could finish it,” shared Saab on Instagram on Monday. “It was after our baby girl’s passing that we learned it was meant for her.”

The writing of the song took only one sitting, and they were off to record, said Jim.

“We couldn't even finish the vocal takes because it was too difficult,” he confessed. “But I guess this is part of grieving and trying to move on: learning to entrust your pain to the people who love you. This song is for our baby Luna and for all those who have lost someone dearly. We'll keep believing.”

This past year, our friendship was put to the test. We tried so hard to be strong for one another. Sometimes to a fault where we wouldn't share our pain to spare the other from feeling hurt again. Then one day, Saab asked me if I wanted to sit down and write our song for Luna. At one go, we wrote and recorded it. We couldn't even finish the vocal takes because it was too difficult. But I guess this is part of grieving and trying to move on: learning to entrust your pain to the people who love you. This song is for our baby Luna and for all those who have lost someone dearly. We'll keep believing. The lyric video is on you tube and the track is on Spotify. Thank you to @kylequismundo for mixing and mastering this song for us and @ma_nichaela @jhengmah for the video.

Despite this ordeal, Saab and Jim were blessed with surviving twin Pancho, whom they named after the former’s late grandfather.
