Those jingles are from a strange 1967 or 1968 package from Heller called “The Greatest Air Show on Earth”.
PAMS did WOWO jingles before that, TM and JAM both did WOWO jingles after that.
Heller did do a nice :60 city/image song for WOWO that I've always liked (“You Can Hear Fort Wayne”) a little before this package. Have you heard that one?
