One of my JW aunts had a fabulous voice and even cut a demo record in the early 1960s. However, her JW parents - my maternal grandparents - and her JW husband pressured her to stop her modest singing ambition because it was a form of self-idolatry and all devotion must go to Jehovah. She even wrote all her own material - unusual for a female singer back then.
By contrast, in more recent years, newer generations of Witnesses have become ambitious in worldly pursuits - and there's no holding some of them back. Good for them, I say! Yet, I feel for the numberless older generations of Witnesses who were "persuaded" to let go of worldly entertainment.
My aunt is still a JW and in her eatly 80s. I haven't seen her for years and wonder, Does she still sing? Or look back and ponder what might have been? How does she feel deep down when she sees the younger generations of Witnesses unabashedly engaging in self-glorification ad in these sorts of slick videos? I don't think she'd decry them their dreams - but I daresay she'd struggle with more than a twinge of envy.
