I've given Alan Watts The Book to at least five people I thought could use it. Four of them never mentioned it again. I'm marrying the fifth next month.

His live lectures, recorded in the 1960s, are great as well. Audible carries various collections: http://www.audible.com/search/ref=a_search_c4_1_16_1_srAuth?...
