Got it recently and read it straight through, on one boring evening at work.
It was the first posthumous collection I've read and I was a little ... hm, worried or something, that it might not hold up to the ones published in his lifetime. Stupid, of course, and after the first few minutes of reading all of that was gone.
I really like it, it was one joyful read which lighted up my whole day and it even contains one of my new all-time-favorite-poems now: My Faithful Indian Servant.
Also it can be an interesting game to play with yourself (if you like to do so) to try guessing out of which periode/decade a single poem is or might be. For some reason I'd have guessed that My Faithful Indian Servant was written in the mid 80`s or even later, but no, all wrong, the famous database tells me: 1962! A real early one.
And Soup, Cosmos and Tears, jesus, here's one for Sheri Martinelli to get pissed upon :)
Much more than Vegas. I wonder, if she ever read it. Truly funny.
