I'm not a huge fan of boiler plate blues imitations by those of the Caucasian persuasion like Ten Years After, early Fleetwood Mac, Savoy Brown, Stevie Ray Vaughn, that goofy guy with the long hair, etc., etc., etc. Unless they transform it into something original like Led Zeppelin, Yardbirds, and Fleetwood Mac in the peculiar case of The Green Manalishi it's just a big yawn IMHO.
Soooo ... Green Manalishi is one of the best songs off all time and my favorite Fleetwood Mac song. My second favorite is Little Lies sung by Christine Perfect (?) in the late 1980's. After that it's a mix of the Yuppie stuff from Rumours, etc. and stuff like Hypnotized, Dragon Fly, whatever.
