Robert Plant has collaborated with West End tenor Alfie Boe, who is best known for his portrayal as Jean Valjean in Les MisГ©rables.

The pair have recorded a cover of Tim Buckley’s “Song to the Siren,” which will surface on Boe’s new album Alfie, to be released on October 31. Plant had previously recorded the song on his 2002 solo album Dreamland.

Boe tells the Sunday Mercury that the two met by chance in a bar and realized they were fans of each others’ work. Says Boe: “There are many people in the music business that I would love to collaborate with – but top of the list has always been Robert Plant. I’m a huge fan of classic rock. To get the chance to duet with him is a wonderful opportunity. It’s fantastic! He’s always been a real hero of mine.”

The Mercury quotes a Decca Records insider who says the collaboration may even lead to live shows. “The exciting news is that this collaboration may soon be witnessed in the flesh, too,” the insider said.
