Dinah Washington recorded this ditty about "her dentist":

LONG JOHN BLUES

I've got a dentist who's over seven feet tall.
Yes, I've got a dentist who's over seven feet tall.
Long John they call him, and he answers ev'ry call.

Well, I went to Long John's office and told him the pain was killin'.
Yes, I went to Long John's office and told him the pain was killin'.
He told me not to worry, that my cavity just needed fillin'.

He said, "When I start drillin', I'll have to give you novocaine.
Yes, when I start drillin', I'll have to give you novocaine,
'Cause ev'ry woman just can't stand the pain."

He took out his trusted drill
And he told me to open wide.
He said he wouldn't hurt me,
But he'd fill my hole inside.
Long John, Long John, you've got that golden touch.
You thrill me when you drill me, and I need you very much.

When he got through, he said, "Baby, that will cost you ten."
Yes, when he got through, he said, "That will cost you ten.
Six months from now, come back and see me again."

Say, you're supposed to see your dentist
'Bout twice a year, that's right,
But I think I feel it bobbin'.
Yes, I'll go back there tonight.
Long John, Long John, don't ever move away.
Say, I hope I keep on achin' so I can see you ev'ry day.

She also recorded a song called "Big Long Sliding Thing", supposedly about a trombonist.
