Neil Young's Rolling Stone
interview concerning this song and album is recorded in Neil Young: Long May You Run: The Illustrated History
: "Tonight's the Night
is like an OD letter. The whole thing is about life, dope, and death. When we played that music we were all thinking of Danny Whitten and Bruce Berry, two close members of our unit lost to junk overdoses. We played Bruce and Danny on their way all through the night."
Speaking of "Tonight's the Night," Young declares what might as well be his M.O. for all of his art: "All of these things happen to people, so I figured it happened to me so I'll write about this, and I'll just write from my heart, and if other people have this happen to them they'll relate to this."
