In an era of upheaval, the image of the Cowsills was so clean, it squeaked, however, there was a dark side to this popular band of the late 60s. Much like reports of the Jackson 5, they had a father that reportedly was demanding and abusive.
This was outlined in the documentary, Family Band The Cowsills, which is available on Amazon's Prime Video. Sadly their image was just that, an image, a couple of them did get into drugs and were not always the ideal kids, although, not all bad.
I was never a fan of the group, which by the way, the TV show, The Partridge Family, was based on, but saw them play in the Happy Together Tour at Snoqualmie Casino. At the time, there were only 3 members left in the group/family. The mom and two of the brothers have since passed away.
