The song But I'm Different Now is performed by The Jam .
Picked you up and let you down and
I never said a word -
But I'm different now and I'm glad that you're my girl
Mess you 'round and upset you I
hurt you most of all -
But I'm different now and I'm glad that you're my girl
Fun lasts for seconds, love lasts for days but
But you can't have both -
And I'm different now but I'm glad that you're my girl
Because I know I done some things
That I should never have done
But I'm different now and I'm glad that you're my girl
