I actually have a bit of Frankie Howerd “gossip”, if it could be called such. Friend and former colleague of mine (bloke in his late 50s now, let’s call him Paul) told me about a veeery unpleasant incident he had at work with Howerd decades ago when he was a younger man (I think about 25 or so?). FH was visiting an establishment in some capacity and my friend Paul was a manager of the establishment in question. Howerd burst into Paul’s office and pretty luridly sexually propositioned him (Paul is straight and I think was possibly married to his first wife at this point). When the inevitable wide-eyed refusal was issued, Howerd bolted the door closed and tried to, er, insist, shall we say.
I’m not entirely sure how exactly but proceedings were interrupted/stalled and my friend was unhurt, but pretty shocked and appalled, as you can imagine!
