I'm almost sure that this whole Ben thing is an April Fools Joke. I don't wanna ruin it if it is but people are really buying into something that doesn't seem right. There's been no word (or even rumors) from Incubus sources, they already have an amazing bass player (and if he WAS leaving, that'd be big news), and Ben seems to be telling people different things (touring with Incubus, doign another album with The Roots, etc). If I'm wrong, I'm wrong...but I ain't believing this one until April 1st.
Maybe Ben was just on some "If I could hear people at my own funeral" type ish.
