Who speaks for Ray-Ray Johnson?

Over in a BBQ Pit thread about pizza delivery Eve says

Did Ray-Ray Johnson have a career and was that really his name? Is Ray-Ray the short, mustachioed man ("oh, ya doesn’t hafta call me Mr. Johnson, you can call me Ray Johnson, or Ray-Ray Johnson, or . . ) from the comedy troupe The Ace Trucking Company, or is/was there another Ray-Ray Johnson?

In Soviet Russia, the Pizza delivers you!

Please tell me there aren’t two Ray-Jay Johnsons! For some reason, The Simpsons writers are obssessed with him. My favorite reference:

Lisa: Bart’s acting funny.
Homer: O.J. funny or Ray-Jay funny?

Jay Jay Johnson, trombone master:

And here is his IMDB listing. I could have sworn he went back farther—there’s just something so 1950s Borscht Belt about him . . .

Ya doesn’t haveta call him Johnson…

Are you telling me that his schtick went beyond “You can call me Ray, or you can call me Jay, or you can call me RJ, or you can call me RJJ…”?
