Wiliam Brady, the manager of several world champs [,Jeffries etc,] gives his account of them here. The first few chapters are about the theatre , but it warms up after that, with accounts of Corbett v Sullivan, Fitz v Corbett ,and so on. http://www.archive.org/stream/fightingman00indirich#page/218/mode/2up
Mc Your post deserves a reply. Interesting story by Brady who saw them all in boxing and was an icon in the Bwy Theatre. Today jim Jeffries is forgotten by fans, but in his day many contemporary boxing people thought he was the greatest....
