Fleetwood Mac is just one of my favorite groups from the 60's. That's right I said 60's. They existed long before their Rumors album came about. That was 1974 and before the Lindsey Buckingham era there was Peter Green.
A lot of artists and their bands have covered this song. Oh Well. and whether you like Leo Kottke and Mike Gordon, The Black Crowes, Jimmy Page, Haim, The Rockets, Lindsey Buckingham or Tom Petty & the Heartbreakers versions does not matter. The point being that they've all benefited from using a song that works and has a great track record. Not a remix but just enough individuality added to differentiate themselves from each other while remaining true to the original.
I'm sure that most of you have played "Whisper Down the Lane" at some point in your life and have laughed hysterically at the end result. This happened because the focus diminishes as the message passes from one to the next. Pay attention to the success of the initial components and improve on them only when applicable. Real Estate is a lot like that too!
