re: Jingles that have endured at least 20 years

The Dallas Times Herald shut down 23 years ago. If you lived in the area & listened to the radio, you will remember their classified department phone number because of their jingle.

"Seven four eight, one four one four
Seven four eight, one four one four
Call the Dallas Times Herald Classifies
for results like you've never seen before."

The paper didn't endure, but the damn jingle did.
