Former Led Zeppelin frontman Robert Plant has collaborated with British tenor Alfie Boe, best known for his portrayal of Jean Valjean in Les Misérables.

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.

In October, 2010 Boe took on the role of Jean Valjean in a concert performance of Les Misérables at the O2 Arena in London to celebrate the 25th anniversary of the show, released on DVD and Blu-ray Disc.
