Metallica worried about sober Hetfield

Metallica rockers Lars Ulrich and Kirk Hammett dreaded the moment frontman James Hetfield returned to the band after recovering from alcoholism - because they didn't want to record an album of "rehab songs".

Drummer Ulrich and guitarist Hammett were so worried Hetfield would enforce his new clean lifestyle on recording sessions for the disc that became St Anger they planned to quit.
