The "Queen" is now heading toward New Orleans. She pulled away from Chattanooga's Coolidge Park docking location around 3:30 this afternoon and shortly thereafter ducked under the raised Market Street Bridge and passed Ross' Landing. Southern #4501 could be heard whistling for Missionary Ridge Tunnel in the distance at some point, which made up for no steam on board the DQ.

Found this in a rather unlikely place: The August 1969 issue of Jazz Journal magazine, pg. 10.
