In subsequent appearances on the same program, such acts took place repeatedly, including breaking The Alfee's set and climbing on top of the cameras.
After performing at the Kudan Kaikan in the previous year, singer Sunplaza Nakano could see the Budokan from the bathroom window and thought, "I wish I could do a concert there".
From this idea, a romantic song was composed as an excuse for empty seats, about a pen pal girl who didn't attend the concert being the reason of it.
The song, "Okina Tamanegi no Shita de" ("Under the Big Onion", in reference to the giboshi on the Budokan's roof) was later regarded as one of their best-known works.
[7] Bakufu-Slump performed in front of a full house at the Budokan and soon after it gradually became recognized as a talented band with a strong rhythm section.
Nakano wrote lyrics to a song composed by drummer Funky Sueyoshi, using Egawa's departure from the band as inspiration, and "Runner" was born.
After Egawa's departure, the substitute bassists for TV appearances included Kazuyuki Sekiguchi of Southern All Stars, Zenon Ishikawa of Seikima-II, Ken Sakurai of The Alfee, Satomi Senba of Show-Ya, Atsuko Watanabe of Princess Princess, Kazuya Takahashi of Otokogumi, Kiyoshi Kakinuma of Stardust Revue, Casiopea keyboardist Minoru Mukaiya (playing synth bass), and Chiba's local talent, Jaguar.
In 1989, after transferring to Amuse, which was effectively the parent company of Daikanyama Productions, the band continued to release hits with "Gekko", "Rizo Raba -Resort Lovers-", and a remake version of "Okina Tamanegi no Shita de" from their 1985 album "Shiawase".
The overseas experience inspired the album "Oragayo 〜in the 7th heaven〜", released in November 1990, which included "The 7th Heaven", performed by Nakano and Kawai at a political demonstration in South Africa.
After "Oragayo", the band released the album "Seishun-Oh" in September 1991, based around the theme of "youth" just like their hit "Runner," but they couldn't achieve the same level of success as with their previous works.
Bakufu-Slump's 1996 single "Tabibito – The Longest Journey" was chosen as the support song for "Saruganseki's hitchhiking across Eurasia" from the Nippon Television's variety show "Susume!
The musicians who agreed to participate were Earthshaker, Nobuya Ikuta (Noise Factory), Shunsuke Ishikawa (Seikima-II), Yuichiro Uchida (Kinniku Shōjo Tai), Tatsuya "Paul" Umehara (44 Magnum), X.Y.Z.→A, Ōsama, Kenji Otsuki (as Sunplaza Koenji-kun); Hideki Watanabe, Tomoharu Taguchi, Koji Kasa and Hideyuki Yonekawa (C-C-B); Yasuhisa Soga (THE GOOD-BYE), Masayuki Tanaka (Crystal King), Demon Kakka (Seikima-II), Hoppy Kamiyama, Masahiro Mitsui (formerly of Tops), Masayoshi Yamashita (Loudness), Lolita No.18, among others.
[8] On January 15, 2013, "Bakufu Tribute Omake Complete" was released with new additions to the aforementioned album, including Ace, Crack Banquet, Rolly, The Captains, Mana Ueno, Ozu, Tatsuhiko Wasada, Kyoji Yamamoto, and Wa-ON (Yoshio Nomura + Rie Chikaraishi).
The event was part of a fundraising campaign to support the band's former bassist Hojin Egawa, who was involved in a car accident in December 2018 and ended up in a coma.
[9][10] As of June 15, 2022, he is still unable to move on his own and it is unlikely for him to return to the stage, but the Egawa Hojin Fundraising Liaison Committee has announced that he has begun rehabilitation.
[12][13] On July 13, 2024, for the first time in 28 years, the four of them appeared together as Bakufu-Slump on TBS TV's "Ongaku no hi" and sang "Ōkina tamanegi no shita de" live.
The tour final performance at Tokyo's LINE CUBE SHIBUYA on November 17 was broadcast live exclusively on Space Shower TV.
