And I am glad you brought these broadcasters to our attention. Radio does a terrible job of remembering its past.
I listened to Lohman and Barkely when I was a kid and they were indeed very funny, although I just considered them to be the KFI morning guys, just like everyone else has a morning show. At that time I didn't really know of or appreciate their longevity. The only difference to me was that they were on the best signal in town, meaning you could literally hear them all over Southern California and most of central California, even during the day. The rest of the names you mentioned I have heard of, but have never heard any sample of their work.
