Guy needs to grow up and sing about something other than high school
You mean like his later albums "The Good Life", "Keeping up with Jones" and "Hard Headed Fool" (surburban life, racial elements, alcoholism and 'soldiers dying in a far-off land).
This knock on CS may have been legit several years ago, but he's done quite a bit since then.
That said, his live shows do always include 21 and Panama City Bound. Maybe Next Year has actually been altered to fit a "middle aged man"
... and Buffett always includes "Fins" and "Why don't we get drunk and screw."
Pat Green gets grief for altering his style over time (selling out), CS gets grief for not.
