The Jingles . . .
WKBO used many jingles during it's years as a Top 40 station.
During The Rock of Harrisburg era, the jingles were from the TM's Phase II package. As Music Radio WKBO, the jingles came from a couple of sources. The Sundance Organization, PAMS of Dallas, and JAM Productions. Here is a small sampling of the WKBO Jingles.
