But that's just a guess.
The trio uploaded a video of them along with Kip Moore and Kacey Musgraves performing Willie Nelson's classic On The Road Again along with the date 7/29/13 and Lady A's website address. I'm thinking that the three acts have a bit of an announcement to make tomorrow.
Perhaps a tour together.
That would definitely be cool.
Just looking and Kacey's last tour date given on her page is October 20 and Kip's is October 11. Lady A, of course, cancelled all their summer plans due to Hillary's pregnancy and subsequent birth of her daughter on Monday, July 22, so yeah, a tour with these three acts could definitely be in the cards.
I'll let you know as soon as I know for sure.
UPDATE: Yep, they are.
