Was thinking about this yesterday. The last collection ended with calls from 2006, so there's a lot of good material to work from. If it were me (and assuming 3 discs could still be done), I'd try to make the tracklist:
Todd Palin
Darren & the Corporate Battle of the Bands
Ken Rogers 1
Philly Boy Roy is a Humanitarium
Rick Stevens (Washington Generals guy)
Ken Rogers 2
Big and Little Bill
Shawn From Rampbridge (plane crash survivor)
Ken Rogers 4
I know we can always listen to archives and Best Show Gems, but there's always something awesome about popping in a CD and hearing the calls in crisp, clear form. Any other ideas?
