I feel soiled. God imagine being on set that day. You'd never stop vomiting.
I thought the video's cast didn't hold any more surprises for me, with its mixture of nepotistically picked Groucho club chums and oddly more recognisable comedians, until someone pointed out that's Robert Popper, later of Timewaster/Look Around You/Friday Night Dinner fame, in the pink shirt:

How many of the original Fat Les group were involved in that song? Just looks like a Keith Allen solo venture ( The video is also misleadingly labelled as being from 2010, when it was in fact from 2002).
I know that Alex James wasn't involved in their 2012 Olympics anthem, recorded as "Fit Les" - it amused me to see it described as "Alex James has left the group", implying the sort of acrimonial bust-up you'd get in an active touring band, rather than just not being interested in recording with a novelty project for the first time in a decade.
