Anyway, 'Aishu Ressha' or 'The melancholy train' was Michi's 13th single and was released on June 1956. And since its a melancholic song, he sings the first few words of the song like he is crying out in anguish.
Its lyrics were done by lyricist Hiroshi Yokoi (横井 弘), who also contributed the lyrics to quite a number of Michi's songs. And the music was composed by... something... Kamata (鎌多俊与). I think it did pretty alright, there wasn't any write up on this song either. All I know is that it was a million seller and landed him his first Kohaku appearance in 1956, and he sang it again at the 25th Kohaku in 1974 after 11 years of respite.
Mihashi, a Hokkaido native, actually kinda began his singing career in 1942 at the age of 12 after winning a Minyo (folk music) singing competition a year before. But he officially debuted in 1955 as an Enka singer with 'Onna Sendo Uta' (おんな船頭唄) after moving to Tokyo to find work, and working at an onsen as a boiler engineer in Yokohama while teaching Minyo. Oh yeah, and Takashi Hosokawa (細川たかし) was a student of his.
Aya Shimazu (島津亜矢), another Enka singer whom I always see doing covers of Saburo Kitajima's (北島三郎) songs also did her own rendition of 'Aishu Resha'. She conveys the anguish well, too.
