While the news is not yet available to the public, Barry Manilow will be touring this coming fall. My source informed me he would be on the East Coast in October, Texas in early November, and hit a total of 24 cities.
If this is true, and I believe it is, the One Night Live show in Las Vegas was in part just a preview and test for a real tour. (Which makes sense, because he definately needs to work some kinks out with the staging.)
Remember, you heard it hear first!
