Vince Clark was only around for the 1st year and split after that. I still wonder why people consider DM a "gay" band - ok sure Mart was into the leather at one time but that was 20 years ago. He grew out of that phase in the late 80s - I don't know how you can call anything from the 90's on up "gay" from Depeche Mode.
Btw - never seen Erasure before but I will agree - Pet Shop Boys in 2006 was a spectacle to the umpteeth degree. I've never seen anything like that before or since.
