The verison of Fleetwood Mac that became popular in the late 1970s was very different than the original version which was a blues band led by Peter Green.
I saw Fleetwood Mac in 1971 – they weren’t a blues band anymore but hadn’t morphed into the popular version yet. The lead singers were Christine McVie and Bob Welch.
A tribute concert was held after Green died in 2020.
Sad!
