Why it keeps Nyad going: "The song least likely to inspire out there would be about heroin addiction in NYC. But it's not the lyrics to this one that move me. It's that eerie, falsetto voice, with the almost quivering vibrato. It mesmerizes me. I'm swept up in that captivating voice."
Lyric to sing to yourself: "I hear you knocking at my cellar door/ I love you baby/ Can I have some more?"
