To be honest, they could just use the 2004 concert footage - still, imho, one of the best edited songs from any concert DVD: .Say Yeah ~Motto Miracle Night~ - MM
Okay, so it's all of Momusu at the time rather than just the original people - but I still think it's great.
Anyhoo - my choices:
- Ikimaashoi
- Suki na Senpai - a 5th Gen PV!!
- Densha no Futari
- Genki+
- Sono Bamen de Bibiccha Ikenai jan
- SONGS
- Jounetsu no Kiss
- Take off is Now
There are others, but these ones would be a good start.
