Maverick Is His Name

I wonder whether John and Sarah know who the real Maverick is? Nevertheless, they are also living on "jacks and queens"

Who is the tall, dark stranger there?
Maverick is the name.
Ridin' the trail to who knows where,
Luck is his companion,
Gamblin' is his game.
Smooth as the handle on a gun.
Maverick is the name.
Wild as the wind in Oregon,
Blowin' up a canyon,
Easier to tame.
Riverboat, ring your bell,
Fare thee well, Annabel.
Luck is the lady that he loves the best.
Natchez to New Orleans
Livin on jacks and queens
Maverick is a legend of the west.
Riverboat, ring your bell,
Fare thee well, Annabel.
Luck is the lady that he loves the best.
Natchez to New Orleans
Livin on jacks and queens
Maverick is a legend of the west.
Maverick is a legend of the west.

an excerpt about the show from wikipedia. I never watched Maverick. I watched the Steve Allen Show instead

Maverick is a comedy-western television series created by Roy Huggins that ran from September 22, 1957 to July 8, 1962 on ABC and featured James Garner, Jack Kelly, Roger Moore, and Robert Colbert as the poker-playing traveling Mavericks (Bret, Bart, Beau, & Brent). Moore and Colbert were later additions, though there were never more than two current Mavericks in the series at any given time, and sometimes only one. Maverick presented James Garner as Bret Maverick (1957-1960), an adventurous gambler roaming the Old West, Jack Kelly as his equally skilled brother Bart Maverick (1957-1962), and Roger Moore as English-accented cousin Beau Maverick (1960-1961). James Garner was the only Maverick in the series during the first seven episodes, and the show is credited with launching Garner's career. Maverick often bested both The Ed Sullivan Show and The Steve Allen Show in audience size. Series creator Roy Huggins inverted the usual screen-cowboy customs familiar in television and movies at the time by dressing his hero in a fancy black broadcloth gambler's suit, an outfit normally reserved in western films for villains, and allowing him to be realistically (and vocally) reluctant to risk his life, though Maverick typically ended up forcing himself to be courageous, usually in spite of himself. The first broadcast episode of Maverick, "War of the Silver Kings," was based on C.B Glasscock's "The War of the Copper Kings," which relates the real-life adventures of copper mine speculator F. Augustus Heinze. The real-life copper king ultimately went to Wall Street. Huggins recalls in his Archive of American Television interview that this Warners-owned property was selected by the studio as the first episode in order to cheat him out of creator residuals. Bret Maverick frequently flimflammed adversaries, but only criminals who actually deserved it. Otherwise he was scrupulously honest almost to a fault, in at least one case insisting on repaying a debt that he only arguably owed to begin with (in "According to Hoyle"). Maverick was not a particularly fast draw with a pistol, but like all TV cowboy heroes of the era, it was almost superhumanly impossible for anyone to beat him in any sort of a fistfight (perhaps the one cowboy cliché that Huggins left intact, reportedly at the insistence of the studio). Critics have repeatedly referred to Bret Maverick as "arguably the first TV anti-hero," and have praised the show for its photography and Garner's charisma and subtly comedic facial expressions.
