More than anything, Ravinia is about enjoying yourself in a relaxed environment. And a night of Joe Cocker's gritty cover versions of songs like The Beatles' "With a Little Help From My Friends" and Dave Mason's "Feelin' Alright" should do the trick. Hopefully, a rainstorm won't cut the set short, as it did during Woodstock - which was 40 years ago this summer, so there might be some great hippie-watching to be had at this one. (Ben Rubenstein)
