What Did I Have That I Don't Have?

I don't know why they redesigned me
 He likes the way he used to find me
 He likes the girl I left behind me
 I mean he... I mean me...
 What did I have that I don't have?
 What did he like that I lost track of?
 What did I do that I don't do the way I did before
 What isn't there that once was there?
 What have I got a great big lack of?
 Something in me that
 He could see that
 Beckons to him no more
 I' m just a victim of time
 Obsolete in my prime
 Out-of-date and outclassed, by my past!
 What did he love that there's none of?
 What did I lose the sweet warm knack of?
 Wouldn't I be the late great me if I knew how?
 Oh, what did I have I don't have now?
 What did I have that I don't have?
 What do I need big supply of?
 What was the trick I did particularly well before?
 What did he see that's gone in me?
 What did I use that now I'm shy of?
 Why is the sequel never the equal?
 Why is there no encore?
 Where can I go to repair?
 All the wear and the tear
 Till I'm once again the previous me!
 What did he like that I am not like?
 What was the charm that I've run dry of?
 What would I give if my old know-how still knew how?
 Oh what did I know?
 Tell me where did it go!
 What, oh, what did I have I don't have now?
