Santana's Black Magic Woman

[BklynBlue]

Yes, it is the same song. Dixon wrote and produced (and I belive played on) the Rush original.
Most of the Rush songs that the Brits covered had some involement from Dixon as he had quit Chess records, to work for a rival start-up, Cobra records, the label Rush was signed to.
"Homework" and the B-side, "I Have To Laugh" were recorded for the Duke label after Rush had left Chess (he joined Dixon, and labelmate Buddy Guy there after Cobra folded)
