I found this in the New York Post

April 24, 2007 — SHERYL Crow should eat crow. The save-the-environment rocker who’s on a “Stop Global Warming College Tour” with Laurie David and just proposed a limit on toilet paper usage is a big gas-guzzler. Her performance rider demands for each show include three tractor trailers, four buses and six cars for her entourage, TheSmokingGun.com reports. She also insists on 12 bottles of Grolsch beer, six bottles of “local” beer and a bottle each of “good Australian Cabernet” and “good Merlot.” Crow’s flack said the rider was “an old one from 10 years ago” but declined to show us a current one.
