Searching in ASCAP today I found a song which feautured Mark Knopfler and Emmylou Harris as performers, written by Richard Bennett.
The title is
RIX RAG https://www.ascap.com/repertory#ace/search/workID/481393455I guess that it's not really a song from "All The Roadrunning", as it's published by "Moderne Shellac" which is Richard Bennett publisher for his solo records. Maybe it was a song left out from one of the Richard albums, maybe it was really for the "All The Roadrunning" sessions but as it written by Richard, the publisher is Richard company... that could make sense as Emmylou's songs appear in ASCAP with "POODLEBONE MUSIC " as publisher, and the MK songs appear with different publishers as well...
