Funny, I have seen those clips quite a few times and it never dawned on me that they were part of a new package, I assumed they were stings and the idents based around the petrol station were still in use!
Yes it was more just an update as all other graphic elements stayed the same (well I've done a mock on it so I should know), the only thing that changed were the idents (with the video posted being cut down versions of the idents used as stings). Not sure whether this happened along with the ident change but the graphics also went into the 16:9 safe area, that may have happened earlier.
Also I'm sorry but this is my OCD kicking in, 623058, 4Music doesn't have the space in-between, sorry but I have to point it out.
