Here is a collection of 35 E4 idents (or more specifically, recordings of E4 idents) which took place ON THE SAME DAY! This appears to be a first for YouTube (as I don't think I've seen anyone else record every ident on a channel that aired in a single day), so this is quite significant! By the way (in case you're wondering), all of these idents were recorded by me.
