   F
At last I found what I was dreaming of

So bad I want to tell the whole world
     Dm
But I won't say no more
                           F
Won't make it harder on you

At last the love that I was dreaming of is mine
                                Dm
Been walking on air for the last 92 hours
                                   F
But I won't make it harder on you girls.


C#
Been groping my way along the darkest of dungeons
B/F
Until I found out there were switches all around.
   F
At last!


F
At last I found I was dreaming of

Someone who truly understands me
  Dm
A man I can trust
                    F
Trust with my dust

At last it's more than I could ever expect

I can't believe it's real
       Dm                                  F
Now my life has a goal, a good happy home


C#
Made up my mind now it's time settle down
          B/F
But don't hold this against me I gotta run now.
   F
At last!


F
Oh girls I found what you're still craving for

If you accept a piece of my advice
     Dm                                           F
It's nothing but luck and I happened to be struck

Oh girls oh please don't be so childish

Don't want my joy to make you sick
          C#
Thought I could share the fun
      B/F                 F
But I guess I was wrong


C#
Gave up my heart and my soul and my pride
       B/F
And my job and my creeds and the ones that I love
C#
Gave up my all to a man I just met
            B/F
But there's no time to waste cos it's almost too late...


   F        C#7
At last !
   F        C#7
At last !
   F        C#7
At last !
   F
At last !
