The bands belted out each other's hits Saturday night; their rendition of "Don't Stop Believin'" could be heard on the streets of downtown New Orleans.
"It's really just a dream come true," said LeVox, Rascal Flatts' lead singer. "You really have to pinch yourself because you can't believe that you're singing 'Don't Stop Believin" and all of the amazing Journey songs that have just been a piece of American music."
The groups said they plan to do some shows together for the summer.
