By this time, woodwind player Thanit Siiklindii (Ajaan) had become a permanent member of the band, and guitarist/vocalist Thierry Mekwattana had joined as well.
This lineup recorded several more hit albums in the 1980s, resulting in a powerful, eclectic and increasingly political body of work, with hit songs like "Welcome to Thailand," "Khon Jon Phuyingyai" "Mae Sai" and "Thaplang".
