Hang on just a minute.

Hang on just a minute.

We have two guests here tonight.

The man who found that song for us, was a man named, Ron Chancey.

He produced most all of our biggest, biggest hits.

He's the one that believed in us first.

His wife is here today on the front row, Linda Chancey, and their sister Judy, give them both a nice hand.

[crowd clapping] Linda and Judy, they're right there.

Thank you for coming.

That's for you.

[applause and cheering] - Oh, what took you so long to book us at The Caverns?

Man, it's so good to be here.

I-I've watched the show on television on the PBS network.

I've seen a whole bunch of people on there, and I wondered why we hadn't been here.

Such a unique place.

I was just worried about the bass singer when he started hitting those low notes.

[crowd laughing] Be careful over there, Aaron.

Wow, this is quite a place.
