This is the WWW page defines Classic Pop not as true jazz nor all big band music, but as what you heard on the radio years ago. It has links to 2 Usenet groups for big band music and jazz as well as several links to online discographies that give transcripts, music bits, and various information about classic pop musicians and singers. There is even a link to Frank Sinatra's own Home Page!
