bbc - you did good! I was interested in the Spanish lyrics, and agree with you that if an author wishes to share his/her work for free that is his/her choice (I typically choose to do so) - but you and I should respect the copyright rules as they exist. I suspect Bill would have been just fine with you posting the Spanish lyric, as you did.
Just for the record, I spoke to him a bit last night; bought the book and a couple of CDs ... I plan to write a quick 'review' of the show in another thread.
