Obviously, I've heard Stairway to Heaven over 50 times in my life like most of us, and I just heard this short piece by "Spirit."
I don't see the connect, but of course, I'm no musician nor songwriter.
Interesting story and I'll follow the suit.
As for Zeppelin copying - ripping off - music from others, there is a very well known book (forgot the name) that notes many of Led Zeppelin's songs were copied / ripped off from some blues player or players.
Anyone know of this book?
