about midday
`` Tell me what the programme is . '' `` At nine the procession leaves St. Peter 's to go to the Lateran -- at least they call it nine . There the Holy Father sings Mass , as bishop in his own cathedral . On the return of the procession , I suppose about midday , the Holy Father visits the tomb of St. Peter . Then this afternoon he is present at Vespers in St. Peter 's ; and afterwards gives the blessing _ Urbi et Orbi _ from the window as usual . '' `` What would you advise ? '' `` Well , I should advise your remaining here till mid-day .
