The show’s getting a pre-Broadway tryout in San Francisco, and “it’s the latest of the Broadway-bound popsicals, those songbook musicals that have been popping up like mushrooms all over the musical theater form.” So how’s it play? “Well, it’s one John Denver tune after another, sung by a cast of six. Diehard Denver fans will miss his uniquely insistent timbre; some may be upset at the ways orchestrator Jeff Waxman has reframed old favorites. Those who consider Denver’s voice akin to fingernails on a blackboard will be relieved by the variety of tones and tempos. But it’s hard to see why they’d want to attend.”
