Why have "Tusk" and "So Afraid" gotten the old man treatment?

[fleetwoodguy79]

These are two of my favorite Lindsey songs, so apologies in advance for the complaining... but...

WHY did he do to these songs on the last couple of tours!? Including the most recent Unleashed tour, he's slowed them down, changed the key, and made them shadows of what they used to be. I can understand why he'd do that to two of his signature songs, and why the rest of Fleetwood Mac would want to perform them that way!?

What is your opinion of the new renditions? Prefer the new arrangement or the original?
