Los Angeles deejay "Emperor" Bob Hudson attempted to substitute for Casey sometime between 1976 and 1978 (no specific date was given); however, Hudson had trouble recording his material for "AT40", giving up after realizing that he could not host "AT40" the same way he would host his morning drive show. As a result, Casey cancelled his vacation and returned to Los Angeles to record that week's "AT40", but made sure that Hudson, a legendary disk jockey and comedian, got paid for his work anyway.
