which person of royalty has "credit down at the grocery store"?

Answer 1

I searched the lyrics you have posted and found this although it's probably not what you're looking for:

Roger Miller - Kansas City Star

Got a letter just this mornin it was postmarked omaha
It was typed and neatly written offerin me this better job
Better job at higher wages, expenses paid and a car
But Im on tv here locally and I cant quit, Im a star

Hah-ha I come on the tv a-grinnin, wearin pistols and a hat
Its a kiddy show and Im a hero of the younger set
Im the number one attraction at every supermarket parkin lot
Im the king of kansas city, no thanks, omaha, thanks a lot

Kansas city star, thats what I are
Yodel-leedle lay-dee, you oughta see my car
I drive a big old cadillac with wire wheels,
Got rhinestones on the spokes
I got credit down at the grocery store
And my barber tells me jokes
Im the number one attraction at every supermarket parkin lot
Im the king of kansas city, no thanks to omaha, thanks a lot

Kansas city star, thats what I are
Yodel-leedle lay-dee, you oughta see my car
I drive a big old cadillac with wire wheels,
Got rhinestones on the spokes
I got credit down at the grocery store
And my barber tells me jokes
Im the number one attraction at every supermarket parkin lot
Im the king of kansas city, no thanks to omaha, thanks a lot

Spoken: stay tuned, were gonna have a popeye cartoon in a minute
