Haven't heard anything about those releases yet, but the "Two April Nights" release probably will contain both the Vegas shows from April first.
One of them "Rockin' April Fools Day" is in the import section. The second one will follow shortly.
If this new release does feature those two (audience recorded) shows it could be a nice release. The sound is okay, at least on the "Rockin' April Fools Day" title and both shows are really good.
