The way they are lined up on the pics over at PSR
The one third from Right appears to be Looking at the guy to his Right as if he´s thinking "drunk again?!"
The pair to the left of the drunk also seem to be Looking on in puzzlement.
The one on the far left Looking at the next one along who also Looks like he´s suffering from the night before.
The Drummer has probably got a Splitting headache due to one too many last night, hence he´s Holding the drumsticks as he is…and slowly seeking the comfort of the Ground to his Right
The Standard bearer is definately using the flag as a counterweight to stay upright.
Discipline seems to have broken down in this Regiment!!!
