From the Wikipedia article:
'First girl I loved', and many other songs, were written before involvement with Scientology. The 'Wee Tam' and 'Big Huge' albums came about during the early involvement. IMO, the ISB initially benefited from their involvement with Scientology as Scientology public receiving introductory-level auditing. And I can remember when their music starting changing, losing its magic and creativity, with the band breaking up soon thereafter. This coincided with the ISB reaching the 'confidential' levels of the Grade Chart. Towards the end, the beautiful mystical poetry was gone - avoided as "R6 bank dramatization" and "mixing practices," etc., followed by several years of musical stagnation in the sterile land of Scientology, followed, eventually, by permanently exiting Scientology.
Scientology, since its inception has used - as in exploited - good ideas and good people. These are scattered amongst the sticky Hubbardian oobleck. By the way, addressing another post, I never stated that the good ideas were original with Scientology, or only to be found in Scientology, quite the contrary.
