The late F. Gwynplaine MacIntyre says the title of the show was Saturday Night Live with Howard Cosell, which is certainly true. The NBC show, however, was called NBC's Saturday Night for its first few months because of the potential title conflict. (I used to vet title conflicts at ABC, although not this one.) Cosell's show was cancelled after a month or two, and NBC "reclaimed" the title not long afterward.
