I won't call Janet Jackson "dumb," but I will say that she is not being very "smart," if she thinks teaming up with the likes of Brian Oxman, LEONARD ROWE, and her brother Randy will do anything to invalidate Michael's will. (Just in case you didn't hear, Rowe recently gave an interview wherein he discussed having a "meeting" at Janet's home with Randy and Oxman to discuss the "fake" will.)
As to the brothers learning from Motown, I'm not sure how those lessons took, but the brothers (aside from Tito) might consider going to Motown summer school. LOL!
I mean, look how much time they ALL wasted waiting for Michael to join them on the stage again. For artist who wanted to remain somewhat relevant, that was not a smart move on their part, in my opinion. If they learned anything it should have been to do your OWN thing while you wait. Especially, Jermaine, who appears to want it so badly.
Jermaine's a decent singer AND plays the guitar. If he had went out there 20 years ago, I'm sure he would have had a measure of success as a solo artist. Sure he would have never acheived Michael's success, but so what, at least he would have been able to etch out a little something-something for himself, career wise.
