Ha! I remember this! This was when they were touring the US at the tail end of the Absolution tour. The time of the setlist anagrams.
They introduced early versions of Assassin, Glorious, Crying Shame and Exo Politics to the crowds in this period. There were muffled recordings going around, and the board tried to decipher them.
These four new songs kept having different names on the set list, a direct communication between the band and the board. Song names were anagrams, which were just fun at first and later turned into a bit of a treasure hunt. (This is where Debase Mason's Grog comes from, for example, a name used for Assassin that's an anagram of Message Board Song.)
Anyway, Glorious at the time was listed as New Song (DES) on the setlist. This was not an anagram, but a note to their roadie, Des, that he had to set something up for that song (A specific tuning for the guitar or something, I don't remember). I speculated that it stood for Dead End Street and trolled the board into thinking that was the actual title. It stuck around for a while. I even heard an anecdote that the band picked up on it and started calling their roadie Des "Dead End Street" for a bit.
Anyway, back to those muffled recordings. In the threads for the new songs there were multiple serious and trolling attempts to decipher the lyrics. Someone heard Pee Candle in Exo Politics, and that was the Muser name for that song for a while.
As for Glorious (Or Dead End Street ), there were many different people trying to decipher a very muffled early recording, and the above interpretation was definitely mine.
Anyway, that's the story kids. Funny this made its onto a lyrics site.
