True story:
When I worked for CS, as PR Manager, at the Shelby Autos facility in 1987-89, I got to know Leno a little bit. He hung around a couple of times, met Shelby, talked cars, etc.
So, one day, Carroll instructs me: "Get me booked on the Carson show when Leno is hosting."
OK, I'll give it a shot.
I call Jay and ask. He thinks it would be fun, but warned that he didn't have a lot of pull as to who the guests were, as it was still Johnny's show, and Johnny would definitely be watching the broadcast, or reviewing the tapes, to see how Jay did.
But, Jay did give me the number of his agent/manager, Helen Kushnick, who apparently did have the pull to book guests. (She later became the show's Executive Producer, when Johnny retired and Jay got the full-time gig.)
She was regarded by many in the business as tough to deal with, and I knew I'd only have about 30 seconds of her attention to make the pitch---and it'd better be a good one.
I wrote out a bunch of suggested talking points for Jay and Carroll, and read them off when I finally got her on the phone. I emphasized to her that Carroll is an icon and hero to an entire generation or two of Americans, as well as a household name to millions of men (and Tonight Show viewers.)
When I got done with my pitch, there was silence on the other end of the receiver.
Finally..."Never heard of her." CLICK.
