Of course it is. It is perhaps the most famous one of all. But I ran into an interesting fact? while searching for an answer to whether Hendrix originated the phrase kiss the sky.
From http://www.kissthisguy.com/jimi.html which is an account of seeing Hendrix in concert conterporaneously with his writing the song, ca. 1967.
I just thought it was interesting that the mis-hearing of the lyric was almost instantaneous and that Hendrix was aware of it and played on the fact.
