The first book that popped into my mind at this hour was the one by Julian Cope, Head On, seeing as how the Teardrops did some gigs with JD back in the day. Haven't read the whole thing in a couple of years, but I did quickly find mention of the YMCA gig that they played with JD, the Bunnymen, and Essential Logic. Cope writes that he bumped into Ian afterward. "He had this deep sad Iggy Pop lament quality when he sang, but he spoke in the most gentle high-pitched Manchester accent. I couldn't reconcile two such different characters in one man".
Seeing as how I think it was Dave McCulloch who wrote that it was the Teardrops who dedicated a song to Ian that fateful Sunday night while they were playing in Scotland, I'm quite sure there's a passage about Ian's death as well. Looks like I'll be reading Mr. Cope tonight.
