Original text

説明不足でした。AとBはテレビのOP曲を歌うグループ(グループ名はABC)のメンバーで今回、正式にデビューすることが決まりました。
おそらくそれほど本格的に活動するグループではないと思いますが・・・。
4人グループで残りの１人はDEFでCと一緒だったDです。
ちなみにA以外は全員Twitterやっています。あとEもTwitterをやっています。

Translation / English

I didn’t explain well enough. A and B are members of a group (called ABC) singing TV’s opening song and their office debut has been decided.
Probably, they are not a group that will be super popular and in much demand.
The last member of the quartet is D, who was in DEF with C.
Incidentally, everyone except for A has a Twitter account. Also, E does tweet as well.

Translation / English

The explanation was not sufficient. A and B are members of group(group name is ABC) that sings them music on TV. It has been decided that they would officially make a debut this time. I think it is not a group that engages in full-fledged musical activities. The other member of 4-person group is D who did activities with C in DEF.
Just for information, all members except A use Twitter. E also uses Twitter.

Translation / English

I did not explain sufficiently. A and B are the members of the group ABC that sings OP of TV. It was decided that they were going to make a debut officially this time.
The group will probably not work so seriously.
The remaining one in the group of 4 members is D who was with C in DGF.
All the members excluding A and E use the Twitter.
