Aitaku natara yozora ni yonde mite
itsu demo yumede modoote kurukara ne
omoide ippai niji iro shabon dama
sabishii kimochi wa onaji sa onaji sa boku date
bay bay bayon ...
hanarete itemo...bay bay bayon kokorowa hitotsu
nakazu ni nakazu ni me-to-me de chikai
mata auh toki made niji iro no bayon ...

hajimete futari ga deaata machi kado wa
higure no niji ga dete ita ame agari
karameta ko yubi ni yasashiku kisu shitara
matsuge ni hirarito hikaata hikaata nagare boshi
bay bay bayon ...
ano hy no koto wo...bay bay bayon wasurewa shinai
anata ni anatani shiawase mitsuke
kaeete kuru kara niji iro no bayon ...

wasure wa shinaiyo donna tooku te mo
kampai shyo mou ichido futari kiri
anata to boku to musunda niji no bashi
hana saku kitetsu ni tsuzukuyo tsuzuku eren ni
bay bay bayon ...hanarete itemo bay bay bayon
anatani anatani shiawase mitsuke
kaete kuru kara niji iro no bayon ...
