There are many reasons I like Leonard Cohen. Primarily his words and music, of course. But here's another.
In 1995, a Finn called Jarkko Arjatsalo launched a fan site called leonardcohenfiles.com, based, as you can guess, on Cohen's work: extensive commentaries, lyrics, and so on, entirely unauthorised. In 1997, Cohen found out about it, and contacted the author... and proceeded to send him much unpublished material (lyrics, poems, drawings, and so on). A couple of years later, he invited Arjatsalo and family for a visit to California. (Source: a recent article in The Toronto Star.)
Contrast with -- for example -- J. K. Rowling.
