Myspace "last name" for my chemical romance?

hey ya all, i want to invite my chemical romance as a friend on myspace, but i dont know what to put as a "last name" i tried everything! from "mcr" or "mychemialromance" "theblackparade" everything! Please help me... the same goes for my other bands as well... like Keane or The Killers or Kaiser Chiefs even James Blunt! (shouldn't we put "Blunt" as the last name?) is there some special code for the "last name" part ? Help would be very much appreciated. Thank ya!
