Gunjō Biyori

Tokyo Jihen was first formed in 2003, after Ringo Sheena decided on members for her backing band for her Sugoroku Ecstasy tour.

The single's B-sides include a cover of the 1937 standard "The Lady Is a Tramp", and "Kao", a duet between Sheena and then guitarist Mikio Hirama, who wrote the song's music.

Pianist H Zetto M gave Sheena a collection of demos before recording sessions started, and "Gunjō Biyori" was the first song present.

Both releases feature an English language cover of an American song popular in the 1950s, and a B-side with a single kanji title.

[10] Tokyo Jihen performed the song at Count Down TV on November 27, 2004, and at Music Station on the 2004 Christmas special, aired on December 24, 2004.

The live performances at the Dynamite Out and Bon Voyage tours were released as videos to promote their respective DVDs.

[15][16] The B-sides were also performed by the band, "Sono Onna Fushidara ni Tsuki" at their Yamabikari, Meet the World Beat and SunSet Live 2004 festival appearances, as well as at the Domestic!

The video for "Sono Onna Fushidara ni Tsuki" is performed on the same set, and features Sheena walking amongst the other band members.

[26] Reviewer Yū Onoda called the single "vivid" and the band's sound "thrilling", impressed by the "punkish arrangement" of "The Lady Is a Tramp".
