Stairway to Heaven = Bridge to Total Freedom

Interesting story from an ex-Scientologist:

Well, I'll tell you what was really written for us....almost half a century ago. Way back when Hector was a pup, the Incredible String Band was very into Scientology and also quite famous. Rose Simpson from Incredible String Band was dating Robert Plant, a member of Led Zeppelin. Robert Plant then wrote Stairway to Heaven, a rather cynical song about buying salvation, which went on to be the number one hit of the 20th century. There's a bit of Scientology trivia the cult would rather forget.
