Best surprise, for a rock concert.....

It sounds awful, but I just wont spend money to go to a concert. While I was in the Army, the USO spoiled me to free concerts.
America. Saw them and they were surprisingly great.
Hank Williams Jr. Awesome!
I saw Johnny Cash while I was in the Army too. That was a great show. He had his wife June Carter Cash and his daughter Carlene Carter also. They made a great show awesome! He really went all out!
I've also seen Yes, Joan Jett, Cheap Trick, Charlie Daniels and the Police.
They were all good.
The one concert that I saw that I absolutely did not like and actually got up a left was .38 Special.
I realize it was a USO gig and it was a freebie, but they were just god awful! Falling over drunk when they came on stage, couldn't finish a song and just generally sucked.
I wasn't the only ones leaving and they saw it. Started yelling at people, that turned me off to them.
