Lyrics:

Well I know lots of the in-crowd, I like to think I'm one
I spend all my winters in St Moritz, just a lazin' in the sun
So I bought Miss '78 Playmate a brand new M.G.B.
But some guy who could dance and kept a gun his pants
Stole her away from me - and mumma tell me why
Some people have all the fun

I wear carefully faded designer jeans and I once met Marlon Brando
And I even bought a drink for the Aga Khan but he would not shake my hand
Oh mumma make me happy, send me lots more cash
Don't worry, I saw the Midnight Express thirty-six times
And I know where to keep my stash - and mumma tell me why
Some people have all the fun

Some guys dance and some girls run
Some people have all the fun - oh mumma
Oh mumma - tell me why-y-y
I spent sixteen grand on an M.G.B.
What else could she want from me-ee
Oh, oh, oh mumma tell me why
Some people have all the fun
Some people have all the fun
Some guys dance and some girls ru-un
Some people have all the fun
So I borrowed Uncle Rocky's yacht to take her sailin' out on the sea
She said you know me, honey, I'd love to come
But can I bring my boyfriend with me, so there we all were in Bermuda
Soakin' up our Hollywood tans
But they kicked over my castle and they sprayed me with sand
I said mumma, I don't understand why
Some people go partyin', some people got mortal sin
But Miss '78 and her neanderthal mate, well they just won't let me join in
Mumma tell me why-y
Some people have all the fun
It's enough to make you cry-y
Some people h
