Cat Stevens is a lost name like Lew Alcindor or Cassius Clay.
There's actually a big difference between Yusuf and Lew Alcindor and Cassius Clay.
Yusuf converted to Islam. Alcindor and Clay converted to the Nation Of Islam, led by "prophet" Elijah Muhammad, whose backstory in Detroit and in the Midwest is staggering and astoudning. That people fell for him and continue to speaks to something and I won't ruin the thread. But Elijah Muhammad's origins as a "prophet" are so ridiculous that to have followed this man takes an extra special credulity or emotional dissatisfaction that is off the charts. Motivating factors can run the gamut, but even those sympathetic to reasoning of the followers often have trouble writing about Elijah qua Elijah. And it's not just because he was a bad dude (he was), it was his background and his theological claims and practices. Hoo boy.
I knew him as Cat Stevens
Makes sense. You only hear about his conversion when it is brought up, which nobody wants to do. For good reasons.
