Lyrics:

Hugh Laurie performed this song, accompanying himself on piano, on the pilot show of “A Bit of Fry and Laurie.” in 1987Mystery
All my life has been a mystery
You and I were never ever meant to be
It's why I call my love for you a mystery
Different country
You and I have always lived in a different country
And I know that airline tickets don't grow on-a-tree
So what kept us apart is plain for me to see
That much at least is not really a mystery
Estuary
I live in a houseboat on an estuary
Which is handy for my work with the Thames Water Authority
But I know you would have found it insanitary, insanitary
Taken a violent dislike to me
I'd be foolish to ignore the possibility
You might have hated me
Still, that's not the only problem that I can see...
Dead since 1973
You've been dead now . . . wait a minute, let me see
Fifteen years come next 'Jan-yoo-a-ree'
As a human being you are history

So why do why I still long for you?
Why is my love so strong for you?
Why did I write this song for you?
Well, I guess it's just... a mystery
