Radiohead's Yorke questions death of David Kelly in song

Radiohead's Thom Yorke looks set to reignite controversy over the death of David Kelly after recording a track on his new solo album implying that the government scientist may have been murdered.

The frontman, an outspoken critic of the Iraq war who has refused to meet Tony Blair, described the song as "the most angry I have ever written".

"Harrowdown Hill" is named after the place where Dr Kelly was found dead near his home in Oxfordshire after being named as the source of a BBC report that the Government had exaggerated the threat posed by the Iraq regime in the run-up to the war.

Yorke said he felt "uncomfortable" about discussing the new song, which will feature on his Eraser album released next month, out of respect for the late scientist's family.

"I'm sure they're still grieving over his death," he told Observer Music Monthly. "I've got this thing where I don't want to make a big deal out of that because ... I don't really think it's appropriate for me to say, Yes it's about that." Some of the lyrics of the song say: "You will be dispensed with when you've become inconvenient ... up on Harrowdown Hill ... that's where I'm lying down ... did I fall or was I pushed."

Yorke said he decided to record his solo album after becoming disillusioned with being with Radio- head, which he said had become "boring".

Asked about the future of the band, Yorke said: "I don't know. I don't think we'd sign to anybody. Give someone a record when it's done if we feel that they can do it justice. That's it."
