Metallica

Metallica rocker James Hetfield is struggling to stay off alcohol as the band embark on another world tour. The singer is a recovering alcoholic, who has managed 12 years without booze.

But he admits its a hard temptation to resist - particularly when the band is on the road.

Hetfield says, "The temptation to drink is with me forever. When you've done something a certain way for so long, doing it a different way is difficult. You start to doubt yourself. I'll never be cured. It's one of those things that I'll have to deal with all my life."
