Johnny More appears to have a cold or other issue with his nose during his routine. When talking about wearing a black Stetson, his finger goes towards his nose and he makes a sniffing sound. Later, around the 12'25m mark, he can be heard snorting while the camera is on Des.
Possibly due to his earlier exertions when singing with Johnny More, Des is noticeably sweating around his forehead during his interview with Kelly Monteith, even dabbing at it with a tissue. Though as he also coughs during the interview, it's possibly the effects of a cold.
