Here is a nice little gem from the mid-70's. The song Why comes from the pre-Stevie Nicks and Lindsey Buckingham Fleetwood Mac album Mystery To Me.
This concert footage is from 1975, so the new line-up is just getting started on their incredible roller coaster ride through the second half of the decade. Rumours and Tusk are still off in the future.
If you are a 1970's version of Fleetwood Mac fan, this track offers a great crossover with the Christine, Stevie and Lindsey signature harmonies taking over at the end of the song. Good stuff.
