The Temptations did okay when they replaced David Ruffin with Dennis Edwards.
Van Halen seemed to do better commercially when they exchanged David Lee Roth for Hagar.
Sabbath seemed to do okay with either Ozzy or Dio.
But all those bands were still at somewhat of a creative point when they changed singers. It was a different time. And Tyler + Perry is the Aerosmith image. But they've been together so long it's probably past time they went their separate ways.
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming
Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
