Act 1 (w/"Up with Hal Gurnee") on Letterman, July 24, 1986 (full, stereo)

After Paul's impromptu snippet of a Parliament classic, the show gets off to a rocky start when Dave confuses Garry "Doo Wop" Shider, sitting in with the band, with George Clinton. It's an embarrassment of which Dave can't let go throughout the rest of the Act.
Then a Top Ten that doesn't go as hoped.
Viewer Mail is next, featuring Jeff Martin as Flunky the Clown,* Rick Scheckman as the apparition of Elvis, and, by request, a performance of "Up with Hal Gurnee" with Laurie Guthrie, Steve O'Donnell, Laurie Diamond, and Joe Toplyn.

In that collection, a You Tube comment from mubd1234:
"Bob Hillman who wrote the [Flunky] letter was the sports anchor for WGN-TV (no network affiliation) in Chicago. He was fired about a year after the segment aired."

Paul's recollection of an argument he and Dave had over Parliament/Funkadelic band members comes from a Cold Close on October 29, 1983, uploaded here: https://www.youtube.com/watch?v=5KjEpa0nt_4

Carey Kirk, the guest with a mannequins demonstration (they can be spotted behind the backdrop during Dave's Opening Remarks), was bumped. He was rescheduled for August 12 but bumped again, and he never appeared on the show.
