When I guest-hosted last month, Kit was 'working from home' that day - which was something of a euphemism by that stage of his illness. And after the show he asked Kit, 'Do you have any more stuff like that?' Kit's 'stack of stuff' was a big part of the show for the next quarter-century. So Kit came on board to deal with Rush's mail, and one day he handed Rush a couple of news stories with a very slender connection between them, and Rush riffed off it for a few minutes on air. But 27 years ago he accepted a job with a guy whose radio show was growing a little faster than he could handle. He had been an actor, dreaming of Broadway, not talk radio. After thinking about it, I figured I must have confused H R with R F, the studio boss of 'Monumental Pictures' in Singin' In The Rain. The dramatis personae of the Nixon White House aren't quite as reflexively familiar to an unassimilated foreign guest-host such as myself, and it took me awhile to get on top of it: on one early show, I referred to him as 'R F', which bemused him. Kit Carson was Rush Limbaugh's Chief of Staff, so Rush dubbed him 'H R' - as in H R Haldeman, who fulfilled the same role for Richard Nixon.
