Sheryl Crow and John Mayer recently toured together and during the next-to-last date, John Mayer come onstage during SC’s set, dressed as a bear. The following night, Ms. Crow interrupted his set, wearing a bikini and waving around a baton (I’m pretty sure she was a twirler in high school). Based on this post from Mr. Mayer’s blog (10/12/06), they had a good time:

“Sheryl – I hope you realize, even if for a fleeting moment just once a day, that everything you’ve ever hoped you would be, you are. I’ve never heard you sing a sour note, your record collection could freeze a Lower East Side hipster dead in his tracks and you have one of the hardest to find traits in a musician; you believe that nice isn’t the opposite of bad-ass. Add to that the great people you surround yourself with, and it’s no wonder I walk away from every conversation with you feeling like I expend twice the energy but say half as much as you do.”

Ms. Crow looks pretty good (for any age). There’s no permalink to the specific post on the Mayer blog.
