Shirley, the Witnesses were/are struck by a fairly routine case of "Chinese whispers" (no offense to Chinese intended)!
Smiddy, Cliff Richard wrote candidly in one of his early autobiographies about his mother being a Witness, whilst at least two of the members of his backing band, The Shadows, became Witnesses - the better known one is Hank Marvin, the lead guitarist who in Britain is considered one of the greatest pop/rock guitarists of all time (Hank now lives in Australia - and there are a few youtube videos in which he is interviewed - in bizarrely luke-warm fashion - about his life as a Witness).
Back to Cliff: He had a brief interest in Watchtower literature in the early 1960s but gravitated to evangelical Christianity in the mid 60s and fervently espoused his beliefs over some decades which did not dent his popularity. He also directly disputed the Witnesses' beliefs on several topics, but I note that in recent years, he's rather toned down his publicly espoused beliefs. Antiseptic best sums up his kind of religiosity - and, at least in that regard, his approach is not dissimilar to Hank's.
