Reservoir catalog track “Rocky Mountain High” has been featured in a commercial by Wonderful Pistachios, the pistachio company best known for its brief advertisements that play on viral topics like PSY’s “Gangnam Style” and the YouTube sensation MysteryGuitarMan. In their most recent spot, satirical news anchorman Stephen Colbert sits on a porch in Colorado and makes a few witty remarks about the benefits of eating pistachios — all while John Denver‘s “Rocky Mountain High” reverberates in the background.
