Ha ha, no problem if you did post it!
Your vinyl collection sounds far more extensive than mine, although I do have the EP you mention, with Dislocation being the fourth track. Systems of Romance is an astonishing album, especially for its time. I've had a delve into my collection and also uncovered a single I'd forgotten about completely, by Midge Ure and Mick Karn.
Anyway, before I feel compelled to ask the mods for an Ultravox sub-forum :)
