Country couple Faith Hill and Tim Mcgraw will perform a rare club gig tonight (18AUG06) at Los Angeles' famous Whisky A Go Go to raise cash for a good cause. The singers will take to the stage for a two-hour show after their Staples Center concert. All proceeds from the $40 (GBP22)-a-head show will go towards the couple's Neighbors Keeper Foundation, which benefits Hurricane Katrina survivors.
