I went to the Tractor's website and found that the band would be joined by the country blues band Cactus Blossoms.
Here's a taste of them for those of you who can't make it to the show.
"Crazy Arms" became a number one hit for Ray Price back in 1956.
It's since been covered by performers as varied in style as Bing Crosby, Chuck Berry, Willy Nelson, Jerry Lee Lewis and Linda Ronstadt.
I think the Cactus Blossoms harmony evokes the sound of the Everly Brothers on this tune and several others I listened to.
Enjoy the show, Dr. Jim, I wish I could be there.
