Eagles co-founder Don Henley testifies in the 'Hotel California' trial

Two co-founders of the Eagles, Don Henley and Glenn Frey, followed a routine while writing their iconic songs in the 1970s. Renting a house and setting up musical instruments, they would spend late mornings discussing song titles, concepts, and trying out riffs. Henley, who paid particular attention to lyrics, saved his handwritten notes in a barn on his farm. Now, these notes form the center of a trial in New York where rare-book dealer Glenn Horowitz and two others are accused of possessing stolen property. Prosecutors claim the notes were stolen decades ago and later sold.
