Just before the 2 minute mark, a cutaway shot of the studio audience sees the camera lurch downwards, before being righted back into place.
During the final sketch with Lex as a drunken character in a top hat, the boom mike briefly drops into shot when he raises his glass to say "cheers" to the barmaids.
When he then sits down to speak to barmaid Kay (June Andrews), the boom mike falls into shot a further three times.
