Where have I heard that before? Part 1

What I do with Hello! Project, I look up the different versions of some ot their songs like, for example, Joshi Kashimashi Monogatari, So i'm looking up the other versions of some of D5's cover songs.

So far, the group have covered Finger Five's Koi no Dial 6700 and Gakuen Tengoku, and TRF's EZ DO DANCE.

So i'm starting with one that i'm sure everyone knows and loves.

Koi no Dial 6700.

This first video is by Gravure Idol Hirata Yuka.
Hirata Yuka - Koi no dial 6700 by kreiskreuz
This video was uploaded in 2008. Not much to say about this. I think she should stick to modeling personally but to each their own.

 Next is the Momoclo Z girls Takagi Reni, Shiori Tamai and Ariyasu Momoka, 2011
 
They are too skinny. Eat more food girls.

Jump back to 2006, a clip from H!P show Uta Doki, Yaguchi Mari and Country Musume

Yaguchi & Country - Koi no DIAL 6700 by YasaSatsu

UFA really need to redecorate that cafe area. they use it was too much in everything they do. It makes them look so cheap.

Linlin's (Morning Musume's really) Version. When I say Linlin's, just watch what she doeswhen she starts the song and you'll know what I mean.
 
That was from their Resonat Blue tour, 2008. Lord how I miss these girls.

Lets not forget D5

Dream5 Koi no DIAL 6700 PV by Kirakira1610
Will forever love this PV, it's what welcomed me into their fandom.

There is another version which was used as a character song in the anime Natsu no Arashi! but i can't find it.

And last but not least, the original by Finger Five, 1973(?)

Finger Five = 4 boys, 1 girl, D5 = 4 girls, 1 boy, Go figure.
