Some out-of-town bands that Granny's 12 Gauge has shared shows with over the years.  Not all have links.  G12G would like to thank:

Nashville Pussy

Master Mechanic
The New Bomb Turks
Dick Diesel and the Mothertruckers
Angry Johnny and the Killbillies
Mojo Nixon
The Cigar Store Indians
The Mount McKinleys
P.W. Long with Reelfoot
The Reverend Nick Barry
Hellbelly
Jack Black
The Sonic Tonics
The Frampton Brothers
The Mudflap Girls From Venus
The Lazy Cowgirls
Big Back Forty and another Big Back Forty link which gives more dirt on the band.  The latter gives the better story.  The two brothers who left the band are from Clarksburg, WV, and have now revived their earlier band Greenhorn, a Columbus favorite.
Monster Truck Five A little mention in a longer article.
Stinking Lizavita
Johnny Mercury and his Hotrockets
The Ubangis This isn't a Ubangis site, but there's a review of them down the page.
Miss May 66
The Fyin' Saucers
The Cowslingers
The Lilly Bandits
Appalachian Death Ride
The Blue Rags

Little Brother's  Not a band but a great music bar in Columbus, Ohio, which G12G has had the pleasure to play at.
