Will they fade???
The Spice Girls seem to think so!!
Once Sporty Spice (Mel C) had this to say in an interview:
“They seem to be breaking America, which we were lucky enough to do. My advice would be just enjoy it, because so often with success like that, it's over so quickly … With pop bands, [fame] is often so short-lived that you have to take every opportunity that you can, and it is hard.”
In other words... save your MONEY!
