[3] He was known to loan his personal phonograph, record collection and even his car to individual listeners under the caveat that they simply return them, which they apparently did.
Among his best-known advertising clients were Matthew’s TV & Stereo ("6400 Mission Street, Top of the hill, Daly City"), Motor Music, Goodies Speed Shops and The Comfort Zone waterbed stores.
He would also make public appearances to promote local Pizza Hut restaurants before relocating to Southern California in the mid-1970s, becoming a ubiquitous commercial voiceover artist.
[5] Campbell also did weekly broadcasts through the Armed Forces Radio Network[6] and visited troops stationed overseas[7] and emceed concerts at Bay Area venues such as the Circle Star Theater in San Carlos, California (Tom Jones/Engelbert Humperdinck), Sandcastle nightclub in Los Altos (Zola Taylor and the Platters, The Coasters and Clyde McPhatter), and several oldies rock and roll concerts with scores of headliners.
Although Campbell never hosted another game show, he was later considered for the emcee position on Sale of the Century and presided over an unsold 1985 pilot for a revival of Gambit.
