Kevin -

That's the song that got me into Neil Young.  I like Cortez the Killer a great deal as well.  Thanks for posting it - due to this thread I'm going to go read 'Shakey'.  (I think sionara is a great play on words as well, Papa Smerf.)  Have you heard Stephen Stills Stills Alone?  Great disc! 

Take it easy.
