Folk icon Richard Thompson is quietly hoping to collaborate with Yusuf Islam.
Fans are often puzzled why the two Brits and Muslim converts have never hit the studio together - and Thompson insists the music world should never rule out the idea.
Promoting his first Blu-Ray concert movie Live at Celtic Connection, he tells WENN, "I would leave that door open. I would think that would be interesting.
"I'm a big fan of Yusuf's from way back and I really enjoy his music. He's a great writer, a great performer and a lovable human being. People really love him.
"But we rarely see each other. I live over here (in Los Angeles) and he lives over there (in Britain), and he was out of music for a really long time."
Both Yusuf Islam, aka Cat Stevens, and Thompson converted to Islam in the mid-1970s.
