On a lined yellow pad, Don Henley, with input from band co-founder Glenn Frey, jotted thoughts about “a dark desert highway” and “a lovely place” with a luxurious surface and ominous undertones. And something on ice, perhaps caviar or Taittinger — or pink Champagne?

The song, “Hotel California,” became one of rock’s most indelible singles. And nearly a half-century later, those handwritten pages of lyrics-in-the-making have become the center of an unusual criminal trial set to open Wednesday.

Rare-book dealer Glenn Horowitz, former Rock & Roll Hall of Fame curator Craig Inciardi and memorabilia seller Edward Kosinski are charged with conspiring to own and try to sell manuscripts of “Hotel California” and other Eagles hits without the right to do so.

The three have pleaded not guilty, and their lawyers have said the men committed no crime with the papers, which they acquired via a writer who’d worked with the Eagles. But the Manhattan district attorney’s office says the defendants connived to obscure the documents’ disputed ownership, despite knowing that Henley said the pages were stolen.
