This song is due to be a Yutaka Kimura Speaks entry in a few weeks so I decided to jump ahead of it with my own take. Honestly speaking, I hadn't heard of this one by singer-songwriter Hiroshi Takano(高野寛)but it has been included in the Top 100 in "Japanese City Pop", so I had to take a gander, especially with the late Ryuichi Sakamoto(坂本龍一)handling its arrangement.
"Yume no Naka de Aeru desho" (We Can Meet in Our Dreams) had actually been meant as a Takano contribution to the vocal group The Kingtones(ザ・キング・トーンズ)as one of their singles, but as circumstances permitted, it ended up getting out as a Takano single in October 1994. Sakamoto and Takano have made it an early 1970s soul single and I can also hear why the latter had wanted to offer it to The Kingtones with their doo-wop balladry. The single reached No. 67 on Oricon and has been included as a track on his March 1995 album "Sorrow and Smile" which peaked at No. 49.
The Kingtones' take of the song did come out in April 1995 as their 29th single. Couldn't find an original recorded version but I did find this concert footage of the guys doing their doo-wop best. As heard here, it sounds a bit more lighthearted but the story is the same: a couple greatly enjoying each other's company on Earth and in the stars.
