We’ve got the full report now from Kenny Chesney’s camp on his show last night at Exit/In:

After a screaming night in Tuscaloosa, Alabama at the Jupiter Bar & Grille, Kenny Chesney followed a #1 party at ASCAP for Mac McAnally’s “Down The Road,” which Chesney and the song’s writer took to the top of the Country Singles chart, with a no-holds bar 4 hour-plus set that celebrated the rock room.

“When you’re coming up and you’re a country singer, the Exit/In isn’t the place you’re gonna get booked,” Chesney laughs. “But when you’re looking for a college bar with a whole lotta history that isn’t afraid to let you turn it up, I can’t think of anywhere else in Nashville you’d go.”

The capacity crowd was not only treated to Chesney and his band working out on hits - ranging from Tom Petty to Alabama to Soundgarden - but they were joined by Nashville’s songwriting elite: Craig Wiseman, David Lee Murphy, Mark Collie, Scooter Carusoe and Brett James.

Beyond Murphy joining the man who’s sold a million tickets for each of the past 7 summers for a revved up “Living in Fast Forward,” the pair dusted off Murphy’s multiple week “Party Crowd” - and Brett James teamed with the 8-time Academy of Country Music and Country Music Association Entertainer of the Year for “You Saved Me,” “When The Sun Goes Down” and a so-new-Chesney doesn’t even know the lyrics “Out Last Night.”

“This is just this wild and wooly thing we do,” Chesney acknowledges of the annual bar run that shakes off any musical stiffness. “We laugh a lot. We play songs we can’t believe somebody called for… and it’s one of the most fun things we do… Normally you do something like this in Nashville, it’s hard to keep it to the fans, but we did… and for all those writers who’ve given me some amazing hits, to get to share a tiny little stage with too much gear, a raggedy set-list and a crowd like this isn’t just crazy, it’s the best.

“I can’t believe everyone who came out and did their songs with me, but it sure was a blast.”

Also joining the melee was Brad Paisley - whose wife is due to delivery their second child shortly - and Tennessean critic Peter Cooper, who threw himself full-tilt into the quick-picking bluegrasser “Uncle Pen.”

“Where else can you hear ‘Fishing In The Dark’ by the Nitty Gritty Dirt Band and Van Halen? We certainly couldn’t do it at one of our shows, but it feels good and rocks hard - and everybody goes home happy. It was after 1 a.m. when we walked off the stage, and if I didn’t have to get back into serious rehearsals, we could’ve played for another hour, hour-and-a-half.”
