Since it's been a while since I've shared...
This is actually my daughter's favorite song by the Doors, when she'll admit to liking them. It's off their 3rd studio album Waiting for the Sun which was released in July of 1968. It was largely considered a "disappointment" at the time, only peaking at 16 in the US (but 1 in the UK). Jim was headlong into his alcoholism and drugs, so this was kind of pieced together however they could. The song itself was written by the band as a whole, but you can obviously hear Jim's contribution through the heavy Native American influences throughout the song. This was a commonality for a lot of the songs that Jim wrote himself due to his belief that the spirt of a Shaman traveled through him after witnessing a car accident when he was 4 years old.
