About the article "Can't Smile Without You", section "Abstract".

Candidate passages:
In the 19th century, most sources for the lyrics do not include music, and those that do often include music different from what has become the standard melody.
Cecil Sharp's "Folk Songs from Somerset" (1905) contains two different melodies for the song, both distinct from the now-standard melody. 
Denise Sullivan, writing for Allmusic, described "Christmas Card from a Hooker in Minneapolis" as "of Tom Waits' most beloved songs from one of his more obscure albums...
The song showcases Waits playing a barroom piano melody, weaving words together -- in essence, doing what he does best in one long, bittersweet song."
