Well, I have tickets to the Atlanta show at the Botanical Gardens, and they are for Friday, July 25th. Ticketmaster.com has Lu in Atlanta on the same date (WITHOUT Mellencamp) as does pollstar.com. Ticketmaster & Pollstar also show Mellencamp playing that same night in Oklahoma City, but without Lu.
BUT, the show list here at lucindawilliams.com shows her playing both Atlanta & Oklahoma City that same night! Must be a mistake, unless something has changed (which I dearly hope is not the case).

EDIT: Just did a little more research – the Atlanta Botanical Garden Web site, like Ticketmaster’s, still shows Lu’s show as July 25th. Hope you have tickets, though – bot show it being sold out…
