Found it, but had to change the lyrics to the original:

Your glory days are over.
Your pilot light is out .
What used to be your sex appeal
Is now your waterspout.

Time was, when of its own accord,
From your trousers it would spring,
But now you have a full-time job
To find the bloody thing.

It used to be embarrassing
The way it would behave,
For every single morning
It would stand and watch you shave.

But as old age approaches
It now gives you the blues
To see it hang its withered head
And watch you tie your shoes.
