Katarina's dad finally succumbed to Parkinson's. It's been a death by inches, so it's a relief to see him finally at peace. Katarina wrote a song originally for her aunt Marjorie when she was near the end of her battle with cancer. She recently rewrote "Go in Peace" to be more general. You can listen to the song on her music page here.
Go in peace, Erik. You are loved.
