Tunes outstaying their welcome

There are two right now: the "Save the Baby" radio jingle and "Noddy Go 'Round the Bird Bath (No, the Bird Bath It Won't Hurt You)," once known under different lyrics as "Sally Go 'Round the Roses" (the Jaynetts). Save the Baby is still manufactured, apparently; it's like Vick's, only less camphory and more herbal in aroma. Noddy Bumppo was the neighbor who drove a Deerslayer (Pathfinder) and obsessively mowed his lawn in ever-increasing circles from his birdbath, for hours at a time, several times a week. Noddy was like a bobble-head doll (hence his apodo, a combination of an association with his vehicle and his physical appearance). He came from Beyond and eventually returned to his mothership. His theme-song remains.
