She's fierce

Beyonce wants to change her name to Sasha Fierce.

If I was to change my name, I think I'd pick: Karl Sound. There's only about a dozen people on the planet that would get that and would know why I would pick that name, but...... well..... there you have it.
(It has to do with the fact that I used to supply the music for some outrageous parties back in the day and that was the hosts' nickname for me at the time - David and Sheilaugh Devlin - are you out there?)
