Fleetwood Mac released this song all the way back in 1969. The song went on to hit number 37 on the UK charts.
However, it wasnt till Santana recorded and released this song in 1970 that it became a massive hit. Interestingly, this song has become synonymous with Santana and is arguably his biggest hit. Santana's version helped boost the album it appeared on Abraxa to number 1. Of course Santan flips this song around. While the original version has a pop rock vibe to it, Santana adds some Latin flavour, a jazz vibe and some mad mad guitar playing.
Both versions are playing today...so which do you prefer?
