Avid followers of Ariana Grande most likely know the TNT Boys — the Big Shot Trio that Grande surprised when they guested on “The Late, Late Show With James Corden” last month.

This group of three extremely talented young singers — Keifer Sanchez (14), Mackie Empuerto (13) and Francis Concepcion (12) — has emerged from an amateur singing competition in the Philippines called “Tawag Ng Tanghalan Kids,” where they contended individually. They have now appeared on multiple international shows, one of them being the global talent competition “The World’s Best.” Here are other interesting facts about the TNT Boys: 

1. They were not the champions of “Tawag Ng Tanghalan Kids.” Kiefer was declared the runner-up, while Mackie held third place and Francis fifth. They rose to fame when a video of them performing together Beyonce’s “Listen” on a local TV show went viral.

2. They hold the record as the Philippines’ youngest sold-out performers and the only Filipino act to have performed on all the four franchises of “Little Big Shots” — US, UK, Australia and the Philippines.

3. They were the winners of “Your Face Sounds Familiar Kids” Philippines. According to the boys, it was much easier for them to impersonate female artists than male artists because of their high vocal ranges. 

4. They joined “The Kids' Choice” Philippines and donated their winnings to a local charity organization known as “Bantay Bata.”

5. When they are not out of the country for shows or concerts, they are regular performers on the Philippine TV variety show “ASAP.”

8. Even with their singing careers blossoming, each of them still have their own dreams. Francis wants to be a surgeon, Mackie wants to be a high school teacher and Keifer wants to be a civil engineer.

9. Each of the three boys has their own specialty when their voices blend. Keifer does the high notes and whistles, Francis sings the melody and Mackie sings the low notes. Francis has the highest pitch of them all.

10. They prepare for puberty by regularly singing high-pitched songs to maintain their high vocal ranges as they transition to this life stage.

11. Among the three, only Mackie has an acting credit so far. He appeared in a 2018 Filipino film titled “Bakwit Boys.”
