Fingernails down the blackboard, or even your eyeballs, are more endurable than this incredibly irritating film about Suzette (Goldie Hawn), an ageing rock chick and ex-groupie in need of cash. She goes to see Lavinia (Susan Sarandon), a former comrade with whom she once screwed rock giants like Jim Morrison and Frank Zappa, who is supposed to have christened them the Banger Sisters. Lavinia is now a respectable, uptight and unhappy mom - so I wonder if kooky, free-spirited Suzette will teach her how to love life again by the final credits?

There's an excruciating role for Geoffrey Rush as the repressed writer whom Suzette must also life-affirmingly thaw out. Like Cameron Crowe's Almost Famous, it is pretty sentimental about what being a groupie actually meant, and also like that film, hard drugs make a single appearance in the form of the implausibly exotic "acid", with which Lavinia's daughter has a U-certificate bad experience. Don't pampered US teens take Es and coke any more?
