If there was a lot of money in the room in the Fillmore Sunday night, an engineering and construction firm that has the London Olympics as part of its client base could drop a buck or two as well. CH2M HILL hosted a day titled “Sustainability in the Rockies” in the parking lot of Denver’s Invesco Field, with a sustainability fair in the day time and a party with Willie Nelson as the featured performer. Not surprisingly, companies that can get Willie to the stage didn’t cut corners anywhere, with lamb lollipops, sea bass and roast beef at six serving stations and two dessert stations.

Nelson’s show was Nelson’s show. He rolled from song to song with only brief pauses for applause, and despite his introduction as someone who has a history of environmental stewardship, he didn’t say anything about the environment. The only time he spoke was to introduce “a protest song,” “Peaceful Solution.” In his populism, though, Nelson was political. His standard set is encompassing, a tribute to the broader American songbook – not just one that includes his songs, but one that treats “All of Me,” spirituals and Kris Kristofferson as equal.
