The version of Bomber-E as broadcast on TV had an interview and only one song, Ikujinashi...
LoVendoЯ[BOMBER-E]...so it looks like the other 3 songs were youtube only, unless they show them on future shows.
Reina had a sudden illness just before Music Festa on April 18th, but the rest of the band appeared and did 4 songs as planned, Kono yo ni..., Ikujinashi, For the future, Iin Janai?, the latter is a new song written by Nakajima Takui, described as having a flamenco style and sounding pretty intense, but no audio is available yet.
