First there is a mountain, then there is no mountain, then there is.

Dude, you're gonna have to ask Donovan this one.

Okay, there's a Myspace page dedicated to the man but it isn't him.



This is his official webpage: http://www.donovan.ie/ (under construction)



Beyond that, you can do a "Donovan Leitch" Google search as easily as I can. His son is DL jr., BTW.
