Here's some cool stuff I've dug up from doing some research.
WBZ - Boston PLUS WBZA in Springfield - Jingle
Copyright © 2009
Most of what I collect is for both WBZ & WBZA
however I'll be posting some pretty cool stuff for Boston's WBZ
as time passes.
Note this department of commerce report from 1927.
It still shows WBZ licensed to Springfield & WBZA in Boston.
