Sir Christopher Lee has celebrated his 90th birthday by releasing a second heavy metal album.

The singer-actor's first creation, which won critical acclaim, was more symphonic than the upcoming Charlemagne: The Omens of Death.

He told BBC Radio 5 live Up All Night's Jamie Stangroom how he got involved in the genre.

Sir Lee's new single Let Legend Mark Me As King is out now.
