What name does Cat Stevens go by now?
I am not really sure.  I think it is Yusuf, a Muslim name for Joseph.
HE was born in UK  and given the name Steven Demetre Georgiou
That's right. That was his given name. But when he became a pop star, at the age of 16, he was going by Cat Stevens. A name a female friend gave him, because of his eyes.
That's sweet!. Are you a fan of his 1970s records?
Yes. There were a lot of great singer songwriters during that era. Cat Stevens sold a ton of records at that time. I particularly liked his "Tea For The Tillerman," album.
Yusuf Cat Stevens remade Tea For The Tillerman a couple of years ago
Quite a few years ago. I saw him in concert, and he was great. He voice was very melodic. I loved his song, "Morning Has Broken." Very spiritual.
I remember enjoying many of his songs on the radio years ago. 
After becoming so famous, he suddenly quit the business because of his new religion, which he still takes very seriously. Fortunately, he has recently returned to touring, so I hope to see him again sometime.
I was sad about that. I hope you get a chance to see him
Thank you. He is so talented, and his songs are really uplifting.
