The booming, boisterous, beneficent and bloody-minded Brian descended upon the studio, and (according to TV legend) proceeded to break all bounds and attempted restrains, temporal or physical. From bellowing "Gordon's Alive!" within the first minute to offering to chin a sitting (in every sense) MP and leaving Paul Merton bemused as to which show he was on, the Blessed one ran roughshod (metaphorically) over the autocue and participants with equal glee. HIGNFY purists, I imagine, may well have hated it, but I know of very few other guest hosts (at least a decade plus on) the public can remember. Apparently, those audience members who had forethought themselves to bespeak transportation had to be paroled considerably before the festivities eventually burned out.
