ok... I know you do have Warp... to recreate it.. you would simply select the area.. I see three areas that have to be Warped...using different settings for the two outside areas.. Inside area, I would suggest you use Arch.. don't worry if it seems to go the wrong way.. just grab the anchor square and drag. it does stop at +- 100% but, if you need more, just accept it  then just keep it selected and do the warp again. I suggest you have a try at the different settings, you can achieve quite a spectrum of effects with it. Lou.

mmm.. looke like I am going to have to PM you the image, sorry
