Pornsak Songsaeng (พรศักดิ์ ส่องแสง), born Boonsao Prajantasen (บุญเสาร์ ประจันตะเสน) in Khon Kaen province on November 2, 1960 and died in Nong Bua Lamphu province on October 15, 2021, was a Thai mor-lam and luk-thung singer who was mostly popular in the 1980s.

After his first mor-lam album, a Lam Long (ลำล่อง) one recorded between 1980-1981, "Suea Sam Nuek Bap" (เสือสำนึกบาป), he began to have success mostly in the Northeast (more commonly called Isan) with his 1982 luk-thung/mor-lam release "Num Na Nakhon Phanom" (หนุ่มนานครพนม).
Followed by several albums after, which met with more or less success, his most popular release which propels him to national recognition throughout all Thailand is "Toey Sao Jan Kang Kob" (เต้ย สาวจันทร์กั้งโกบ). Released in 1986, its success even led him to perform alongside other artists, especially Bird Thongchai, another rising star at that time, in 1987.
Two years later, in 1988, he released "Lam Phaen Khon Klai Ban" (ลำแพน คนไกลบ้าน"), another successful album following Toey Sao Jan Kang Kob. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
