Umm No, Milli Vanilli got whacked because they NEVER sang their songs in the first place. Other artists recorded the music and they where nothing but a completely fraudulent front.
Plus, if you read the article you will see that the singer was actually singing, he was just singing to a backing track while the band members pretended to play.
Looks like a matter of degree, rather than substance. Maybe RHCP should lose one of their minor awards, rather than one of their Grammys.
