Just found this really cool vid on Youtube. Thanks to the originator who posted this. I remember a report of Akina singing Kyon’s 「なんてったってアイドル」 dressed up like Ann Lewis. I can’t recall if I have seen it though.
Anyway, here’s Akina with Ann herself dueting on three of Ann’s rock hits. A bit too noisy for my taste but I like the energy. Enjoy!
