"We took advantage of the possibility of bringing so much focus, attention on things that need to be discussed," said Graham Nash. "It's a different buzz with CSNY, with all four of us."
Nash says the quartet has rehearsed all of the songs from Young's politically oriented new album "Living With War," including titles such as "Let's Impeach the President" and "Lookin' For a Leader." The 34-date trek, which starts Thursday in Camden, N.J., will also feature older favorites like "Wooden Ships," "Find the Cost of Freedom" and "Ohio."
Nash said he's also written a new song, "In Your Name," which deals with the idea of killing in God's name and may be debuted during the tour.
It's the first time CSNY has toured together since 2002.
