Hello!
No videos yet, but it was the lounge-y, jazzy version she's been fond of recently--I thought it sounded great! The bassist and drums were members of a band called Okamoto's (Hama Okamoto and Okamoto Reiji, respectively), Hiizumi on piano, Ukigmo on guitar, Murata on trombone.
She went up before Aiko, who described how Ringo was so cute before debut, and used to wear her hair in twin tails, and Ringo told her to stop bringing up her dark past
I know everyone jokes about her going granny, but I get the impression that she's trying to create a polite distance between her personal life and her work, because she's very playful when people she's familiar/comfortable with are on shows with her
Her outfit was as seen, black hate, pink sleeveless turtleneck, black skirt with harness (?), very pretty, very good
