A volunteer helping to sort through the rubble left behind by the recent tornado that struck Moore, Oklahoma stumbled across an ancient country music artifact -- a cassette copy of Reba McEntire's 1987 album 'The Last One to Know.'

The bemused singer posted a picture of the find to her WhoSay account, writing, "Talk about full circle! A tornado cleanup volunteer found a REBA tape in the midst of the wreckage."

Now if only someone would unearth a working cassette player from nearby, at least the volunteers would have some great tunes to listen to while they're helping their friends and neighbors try to sort out the mess left by the Category 5 tornado that touched down on May 20.

Of course, McEntire showed up in person on Wednesday night (May 29) at Blake Shelton's 'Healing in the Heartland' benefit concert, where she sang a rousing version of 'Everyday People' to raise money for disaster relief for her fellow Oklahomans.
