A little harsh on Al Murray. At least he's funny. Keith Lemon has a similar sort of act, but sucks at every level, as do his other personas.
As for Sum Of The Parts, there were probably loads of people who ended up on the cutting room floor, (along with the whole of Steve's massive solo career which probably outnumbers the rest of the band members in total albums recorded terms) to make room for the 4 talking heads who were hired to fill the show with their vacuous "weren't even there at the time" comments.
I hate Keith Lemon to a passion!
