You know those jingles you hear on the radio – the ones that sing the call letters of the station in the style of the station you’re listening to? Like, WKRP in Cincinnati… or 102.1 Kiss FM…well, those kinds of jingles were first created here in Dallas decades ago. And one of the gems in this town who is a jingle creator, producer, historian, and guru is Jon Wolfert, owner of JAM Creative Productions. Check out Jon’s interview with Rosana (who has sung jingles at JAM for many years). They talk jingles, the biz, Rosana’s musical history, and they even hear jazz vocal legend Sarah Vaughn sing a commercial jingle!
