Must be the same version, how many could they have done?? if its the one on that groovesville masters CD, the blue one with Edwin starr - has it happened to you yet, then yes the very same version..
I've never owned the revilot single so i cant say for certain, but recordings I had always sound dull to my ears, where as the other above version sounds clear and crisp, even if, as you say, they dont know the words... Never struck me that way
I could always buy one of those round table mats with the label scan on, while playing the other version...cheaper again..
