Mark Hennessy (author)
Mark Hennessy also writes poetry in addition to lyrics. I think his first book was The Caretakers, but it wasn't really published or anything.. he probably just got a few copies printed up to give to friends.
Cue The Bedlam (More Desperate With Longing Than Want of Air) was published in December 2005 from Unholy Day Press. Unfortunately, even when it first came out it was hard to find, and now it's just about impossible, but you can learn more about it and hear clips of Mark reading some poems here: http://www.lawrence.com/news/2005/dec/15/cue_bedlam/
