What Did I Have That I Don't Have?

What did I have that I don't have?
What did she 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 she could see that
Beckons to her no more
Oh, I'm just a victim of time
Obsolete in my prime
Out of date and outclassed by my past
What did she love that there is none of?
What did I lose the sweet knack of?
Wouldn't I be the late great me if I knew how?
Oh, what did I have that I don't have now?
Tell me, what did she like that I'm not like?
What was the charm that I've run dry of?
And what would I give if my old know-how still knew how?
Oh, what did I have that I don't have now?
