Please allow me to try and explain
I'm living proof that man can change
I knew what I wanted
I knew how to get it
It didn't make it happy so I started again
What I wanted to be was a family man 
but nature had some alternative plans
So I did without the lot put emotion on hold 
and hoped my instincts would do what they were told

I wanna know yeah
I wanna know

But every now and then 
often at night 
a particular feeling would surface in spite 
of what I told myself and tried to deny
I kept on asking the question: why?

I wanna know yeah
I wanna know

You grow up and experience this 
a total metamorphosis

It's all about change
It's a metamorphosis

With time and age I had to change 
'cause my behaviour was getting strange
People on the street caught my eye
and I began to think I might be their kind of guy
The long-term suppression of an adolescent urge
was in retreat and I was on the verge
of falling in love or having fun
Time was running out
Something had to be done

I wanna know yeah
I wanna know
I wanna know yeah
Tell me what's the reason

Where was I?
Laying down the law
dancing with others
out on the floor
Music and smoke
What did it mean?
Somebody spoke and I went into a dream
I had what I wanted
madly in love
Nothing else mattered
This was enough
Questions were answered 
which used to perplex 
in particular those about the big s.e.x.

I wanna know yeah
I wanna know
I wanna know yeah
Tell me what's the reason

You grow up and experience this
A total metamorphosis
It's all about love
It's a metamorphosis

Dreaming is easy
life is tough
I got the picture
The most important thing 
is not to end up bitter 
'cause when you start to feel 
increasingly forlorner 
woomph! love comes 
right around the corner
It may not last 
but here am I
once a caterpillar
now a butterfly
It can seem strange
but when you reminisce
