Connection with Rammstein
After Roland and Till met each other the first time, they found out that both get along well, and Till is a fan of Rolands song "Manchmal möchte ich schon mit dir" (Sometimes I want to do it with you), they agreed on working together. But instead of singing a song together Till wrote a song for Roland. The song is called "Ich weiß alles" and is about a guy who knows, that his wife is cheating on him. It was released in 2014 on his album "Seelenbahnen".
