Production Crossing Jordan was created by Tim Kring and was produced by Tailwind Productions in association with NBCUniversal. Singer-songwriter duo Wendy and Lisa scored the music for the show. Eric Rigler's pipes and whistles can be heard in most episodes. The scientific aspects of the show are comparable to CSI: Crime Scene Investigation, but Crossing Jordan is more character-driven and less graphic than the CSI franchise. In the first season, Hennessy was the only cast member visible during the opening credits, which featured Eric Rigler's arrangement of a traditional Irish tune "The Boys on the Hilltop" (a quicker tempo, but shorter version of "Reels Part One -- The Boys on the Hilltop" from the Bad Haggis CD Trip). Starting with the second season, the credits showed all the major players and used a more rock-like, less-Irish-sounding opening theme. Crossing Jordan is set in the same fictional universe as fellow NBC series Las Vegas. In the season-four episode "What Happens in Vegas Dies in Boston", a case takes Jordan and Woody to Las Vegas, where Woody became very well-acquainted with the Montecito's casino host, Sam Marquez (Vanessa Marcil). They maintained a long-distance relationship for a while: O'Connell appeared in five episodes of Las Vegas and Vanessa Marcil appeared
