This song was composed specifically to be used as the signature tune of His Majesty’s Aw.Saw.Friday Band and was always played as the band’s final number.

The English lyrics of “When” were composed by Mr.Raul Manglapus, an ex-Congress Member of the Philippines. The Thai lyrics of “Klai Kangwol” (which translates as “Far From Worry”) were composed by Mr.Wichai Kokilakanit.

Mr.Manrat Srikaranonda commented:

“His Majesty wrote “when” at Klai Kangwol Palace, at a time when patriotic music was popular, encouraging a spirit of national unity. Her Majesty the Queen then sought permission from His Majesty to have Thanpuying Maniratana Bunnag write another version of the Thai lyrics, “Kerd Pen Thai, Tai Pua Thai” (Which translates as “Born Thai, Die for Thailand), “When” became the band’s finale. When His Majesty’s audience heard this song, they would know that the party was over, and they would start to line up for His Majesty’s departure. Then His Majesty changed and improvised the song, after playing the revised and unfamiliar version, His Majesty packed away his musical instrument, and told the audience that that was it. The audience later caught on, and when His Majesty played only one note in the chord of E Flat they would know that it was the final song of the evening performance.”
