Oh, please don't let me down! We put ourselves out into the world after preparation, training and time, hoping our dreams can one day be attained! What state do you find yourself while listening to this song? I can't help but be completely charged and ready to embark on a new adventure. "Don't Let Me Down" was recorded in 2969 during the Let it Be sessions, written by John Lennon and Paul McCartney. Of course on the keys, Billy Preston.
