Always loved this tune, and the marimba adds that unique early/mid '60's Stonesy vibe ala Under My Thumb.
Can't recall the first time I ever heard it, but it's fits in the same category as all the other classic Stones "oldies" as if it's always been there.
Has a unique Motown essence - especially in the chorus, and the lyrics are quite good and biting "You're obsolete my baby ".
As for Chris Farlowe and his version, never heard it until probably a decade ago. I don't think he ever quite made it here in the US - ever.
Doesn't bother me that they haven't played it live, and especially in the latter era as they probably would have butchered it to death.

Rip this joint, gonna save your soul, round and round and round we go......

Saw Chris serveral times during the past 15 years performing Out Of Time, and he always thanked the Stones for writing "his song" .

Keep on rollin'

I don't know how well this would work in a stadium.

maybe if they did it as part of the acoustic set somehow?
