Thank you matonanjin2.

Do you know I'd forgotten about the Santana cover, and shouldn't have as it released at a salient time of contemporary music awareness for me in the late 70's, with so many epic bands' music in their heyday. ie. Eagles, ELO, Chicago. I like/d Santana, and also liked their adapation of "She's Not There" at that time it released. Worthy of honourable mention, but different.

That said, like many songs subsequently released as covers, for me this is one of them where the arrangement and delivey of the original is unsurpassable. Another is "You Really Got Me" by the Kinks.
