Write a feature that begins with the moment Gene Simmons lands two Ace Frehley songs in his live set and use it to explore why fans clap hardest for “what could have been” in band history. Weave in a concise primer on how song authorship, performance rights, and set-list choices shape fan memory and legacy. Include at least one quote or paraphrase from coverage about the reception and controversy, and comment on how nostalgia influences modern rock fandom. Conclude with a short reflection on what this moment reveals about intergenerational influence in music.
