เนื้อเพลง สัญญา - หิน เหล็ก ไฟ

mae non rue yang pho nueai haimai mai tong ro khao non kotai
ik mai nan cha klap pai ko ru di wa huangyai

thi laeo ma mai khoei fang khrai ao arai cha ao hai dai
wan ni mong sawang khaochai ko rutua wa phit pai

to pai cha pen luk thi di cha tham nathi luk hai sombun

yang pen dek noi khong pho samoe yang non lamoe hai mae khoi plopyon
cha pen dek di hai pho phumchai cha pen khon di khong mae talot pai sanya

o chiwit khon dinron khwai khwa chon luem wan wela phuea hai
khwam samret man yu thihai ying nap wan ying ba pai

to pai cha pen luk thi di cha tham nathi luk hai sombun

yang pen dek noi khong pho samoe yang non lamoe hai mae khoi plopyon
cha pen dek di hai pho phumchai cha pen khon di khong mae talot pai sanya

yang pen dek noi khong pho samoe yang non lamoe hai mae khoi plopyon
cha pen dek di hai pho phumchai cha pen khon di khong mae talot pai sanya
