This radio workplace sitcom was as disposably ’70s as the loud patterns on Herb Tarlek’s leisure suits, but it was something more too. It’s probably best remembered for its gut-busting stories of office hijinks and promotions gone wrong (“As God is my witness, I thought turkeys could fly!”). But it was an underratedly smart show, infused with a sense of things ending—especially, the free-form, anarchic, album-rock ’70s. (One of its most moving episodes was about the 1979 Who concert stampede disaster at Riverfront Stadium.) From its wistful theme song—”Just maybe think of me once in a while”—to its setting at a small-market station past its heyday, WKRP mixed a few bittersweet notes into its playlist of savvy comedy.
