[13] The song was performed again during the Mind Travel Release Commemorative Free Live at the Yokohama Red Brick Warehouse on June 15, 2011, footage of which was shown on the "Ai o Kurae" (2011) single's DVD.

[14] It is made up of recording studio footage, altered to look like a video taken in the 1960s, with additional effects such as lasers, pencil-drawn triangle art and space imagery.

Many of the instruments were also praised, including the "dancing" guitars and hammond organ, however Tatsuya Nakamura's drums were singled out as "wild and tight", and what pull the song together.
