Hi DJK,
Well, I would be here all day if I went down the friends and family road, so I won't as I'm sure we'd all be the same and would bring all of our loved one's back.
So I'm thinking of my comedy hero, the amazingly talented Ronnie Barker, I'd also get back that corner of my heart that broke when he sadly left us. Also John Thaw, what a brilliant actor. I'll stick this one in for Roy, he would choose Elvis. And lastly, if I could bring back a fictional character it would be Macbeth, I just love it and I'd ask him, "What the hell happened back there?" 
Tomorrow girl I'll buy you chips, a lollipop to stain your lips :-)
Happiness is wanting what you have, not having what you want :-)
