Last night at the Wash.DC concert, Pieta said that when she was younger, she came across a cassette tape somewhere (?), and she listened to it. She was blown away by it, and kept listening to it over and over and over again. It turns out it was a DS tape.
She mentioned that she has been so moved by the music of MK and the band on this tour, that 3 nights ago, she went to her dressing room and wrote a song about him (them). She sang the song last night. I was unable to understand any of the words though. Maybe someone else who hears her soon will be able to understand them better than I could.
