..."Take that microphone off of the stand, hold it upright just below your mouth and sing over the top of it"...

Are you the guy that advised John Major on microphone technique during his orange box/ save the pound bus tour?

The technique you mention DID enable JM to make himself heard above catcalls like 'Oy John! Still shagging the cook...?' and similar witticisms and pleasantries, but he didn't half look a prat. Although to be fair, JM got it a bit wrong and held the microphone under his nose.
