BACKSTAGE PASS

The all-American boys in Creed scarf down beef jerky and drink Hi-C at shows. The Foo Fighters will never share a dressing room -- unless it's with Supergrass, Oasis, ''or maybe Led Zeppelin.'' And P. Diddy contractually requires that ''all food and ice must be inspected for hair'' before being served. That's a sample of what you'll find in just 3 of the 130 ''contract riders'' -- backstage demands artists submit to promoters before a show -- that have been collected in The Smoking Gun's dishy series documenting rock-star excess. How do the Gun-ers manage to get their hands on these confidential contracts? That's one of the music world's best-kept secrets.
