That's saying that mediocrity is acceptable, although I agree with PN re needs to be backed up by a team feeding the correct information on who is coming into the shot. PPPP = PPP
"have no concept of the pressures of live commentary". I think shouting orders out from memory on a public parade ground at a graduation or other, very public parade in the correct sequence in front of the general public and higher ranks would be more pressure than live commentary where you have back up staff and notes.
Not sure what the UK marches and broadcasts are like but the whole sequence is known in advance here and published. Can't be too hard to do a bit of background research.
Just my HO.
