Back on the Dance Floor Lyrics

Cover art for Back on the Dance Floor lyrics by Mark Knopfler

Assume from the high roller stetson (began as a gambler's hat style in the late 1800's), the smokeless 41 ( a Colt '41 first manufactured in 1877; smokeless propellants came on the scene in the early 1900's), the dressy two tone wingtips (popularized in the late 1860's from cricket shoes), and the skull head walking cane (simply an added bit of stylistic finery), that this is simply a song about a gambler and his pals (women included with moneymakers to shake) heading out for some action after a time away from it (back on the dance floor, metaphorically). What I want to know is, what is a knocked-out boogie shack? That connects, non-metaphorically to dance floors, of course, but not to gambling per se. Major comeback? Has the gambler been in prison?
