My band I had about 7 years ago opened up for Rascal Flatts and the Bellamy Brothers. I've also sat on a tour bus and passed around a bottle of Crown with Tracy Lawrence, Tracy Byrd, and Mark Chestnutt. I've hung out with Johnny Lee, Earl Thomas Conley, and actually sang a song with the Sons of the Desert guys on their tour bus. This was all down in Corpus Christi, TX.
Good times.
Edit: Also used to get drunk and party with Johnny Rodriguez. That guy's a riot.
