Between Seventeen & Twenty lyrics

Music by elton john, davey johnstone, and caleb quaye
Lyrics by bernie taupin
Available on the album blue moves

I wonder whos sleeping in your sheets tonight
Whose head rests upon the bed
Could it be a close friend I knew so well
Who seems to be so close to you instead
Close to you instead

Im blue tonight, Im red when Im mad
Im green when Im jealous, yellow when Im sad
I guess I cannot have everything
So much has flown between the years
When I was twenty and you were seventeen

So out of choice I chose rock and roll
But it pushed me to the limit everyday
It turned me into a gypsy, kept me away from home
From there on, there seemed no use for you
For you to stay

And if I shower around 3 a.m.
Its just to wash away
The trace of a love unwanted
Oh in the times I went astray
The times I went astray

So much has flown between the years
When I was twenty and you were seventeen
