I'm really looking forward to this event. If I still had my Sailormoon: Piano Fantasia CD, I'd totally loan you out the tracks. Much of the arrangements of the TV songs have been set to classical piano arrangements.
Ein No Melody - total must have for the ballroom dance! (I'm probably biased because I'm the resident Rei...)
Starlight Rain - great for west coast swing / hustle combo
My Only Love - yes, the one from the dub.
