The melody was composed by Phra Chenduriyang (Peter Feit), and the official lyrics were written by Luang Saranupraphan.

Changwang Tua Phathayakoson (จางวางทั่ว พัทยโกศล) composed a tune in a traditional style called Phleng Maha Nimit, but Phra Chenduriyang's melody was selected because it sounded more modern.

Even though the Thai disaster is inferior But still able to restore the independence back It is an honor to the beautiful Ayutthaya That is not an end to good people.

All of us, we are of Thai blood Doesn't allow anyone to oppress us Protect rights and freedom When disaster helped each other until the day of death

If we die, the name will be spread That Thailand is firmly in love with the nation Have great friendship for both men and women The glory of Siam will never be lost, Hurrah!
