its the same song all done differently , i like them all , they all bring something different to it ..i brought shitness to it. Nina simones is just controlled soul pouring out on that vocal. Bind willy johnston adds real felt grit and hardship in his version, led zeppelin just rock it to bits (in a good way) expand it in your mind with the trippy guitar rifts , they are all excellent. i will listen to the willie nelson and tom jones ones now didnt know they had done versions
