There will be a last song played on 106.7 forever. Even if Cumulus cans news by then the station will be on 106.5. My first though was "Atlanta June" from Pablo Cruise's Place In The Sun album. The song does have a few lines about coming back so it might not work. Has any station ever used Steam's Na Na Na Good Bye? For technical reasons a really long song Rare Earth's Get Ready (Album version) or Iron Butterfly's "In-A-Gadda-Da-Vida" could work. When I flipped WIKI from AC to Country I used Rapture by Blondie for the extra time to change out a whole bunch of carts.
