The Roundabout Theater Company’s Broadway revival of “Cabaret” will get a national TV spotlight later this month when “The Tonight Show Starring Jimmy Fallon” hosts a performance seg from the tuner featuring star Alan Cumming and other members of the cast.

As the host of “Late Night,” Fallon made a habit of incorporating Broadway perfs into his show, particularly in a “Broadway Week” series of segs from productions including “American Idiot” and “Anything Goes.” The minute the Gotham relocation of “Tonight” was announced, with Fallon as host, all of Broadway spied a prime opportunity for national TV exposure.

Toplined by Cumming and Michelle Williams, “Cabaret” is the first Main Stem title to snag a dedicated slot on Fallon’s “Tonight,” a score that looks even more valuable given the show’s recent run of boffo ratings. Before this, Broadway tuner “If/Then” got a tangential publicity boost from the recent appearance of “If/Then” topliner Idina Menzel, whose “Tonight” performance of her breakout song from animated hit “Frozen” went viral.

If “Tonight” starts to book Broadway on a regular basis, the show could become a new go-to for Rialto TV appearances. It’s worth noting, however, that Main Stem shows are featured with some regularity on “Late Show with David Letterman,” and many in the industry agree that those segs don’t drive sales as much as performances on morning shows. Those skeins — such as “Today,” “Good Morning America” and “The View” — generally play to older-skewing female auds, which is Broadway’s prime ticketbuying demo.

The “Tonight” gig for “Cabaret” is set for April 10. NBC didn’t announce what number will be showcased, but it’s said that Cumming and the show’s chorus members will perform tune “Wilkommen.”
