空模様なんて 気にもならない
なにしろ 今日は最高の日さ

願いをこめて その人を吹き消してごらんよ
新しい日がまたはじまる 用意はいいかい

Happy birthday, happy birthday
Happy birthday オメデトウ
Happy birthday to you (今日はサイコー)

この世に生まれ ハデに泣いてから
月日とともに きみはステキになる

悲しみがあるなら 一緒に吹き消してみようよ
大丈夫 もうひとりじゃない 用意はいいかい

Happy birthday, happy birthday
Happy birthday アリガトウ
会えてよかったよ

ラララ 時が過ぎても
ラララ 今日を忘れない
ラララ 時が過ぎても
ラララ 今日を忘れない

Happy birthday, happy birthday
Happy birthday オメデトウ
Happy birthday to you

Happy birthday, happy birthday
Happy birthday アリガトウ
Happy birthday to you (今日はサイコー)

Happy birthday

B’z

B'z is a Japanese duo rock band formed in 1988, consisting with Vocalist & Lyricist Koshi Inaba (稻葉浩志) and Producer Tak Matsumoto (松本孝弘), currently belongs to VERMILLION RECORDS under Being, Inc.

Originally they planned to name the band “A'z”, means A to Z, which means “Include everything from A to Z”. But A'z has been read as AIDS, and many other reasons beside this. After they discussed, they decided using “B'z” as the name of the band, because B is after A.

B'z released both their first single “Dakara Sono Te wo Hanashite (だからその手を離して)” and their first studio album B'z on September 21, 1988.
