When it comes to performer's names, I always think the champ is Tiny LaVonda. She was a sideshow dwarf of the 1940s whose story will break your heart: http://www.phreeque.com/tiny_lavonda.html .
I always wonder if Jah Wobble would be more respected if he released his many excellent dub/world albums under his real name of John Wardle.
It was a drunken Sid Vicious who garbled Wardle's moniker into Jah Wobble, and the new name served him very well in his early days simply because it was so memorable. Dropping it now would simply confuse everyone, but I suspect many people still dismiss Wobble's records as a joke simply because of the name he releases them under.
