Secret lives under ‘e.u Band’ ?
Some rumors are saying that YUI is doing secret lives under a band named “e.u Band“.
e.u. (Spell it in English)
イーユー
u.e. (Spell it in English)
ユーイー
YUI !
e.u. is in fact YUI in reverse.
They apparently performed twice in live house with this Set list:
1. Laugh away
2. 雨上がりの夜空に
3. Rolling star
4. I’ll be
5. Love is all
6. again
7. Sea
In this band the drummer is replaced by the girl drummer saw in Rolling Star, I’ll be and again.
