Regarding the title track >>>
In the liner notes of The Very Best Of, Frey had this to say about the song:
We had Don Henley's voice, which allowed us to go in a more soulful direction, which made me exceedingly happy. A lot of things came together on One Of These Nights – our love of the studio, the dramatic improvement in Don's and my songwriting. We made a quantum leap with "One Of These Nights." It was a breakthrough song.
It is my favorite Eagles record. If I ever had to pick one, it wouldn't be "Hotel California"; it wouldn't be "Take It Easy.
