We built a fort inside your room
We walked around this town
Made out like bandits in the gloom

Where have you been so long so long
I've waited oh so long for you
I've got ta figure out
Just what this means and what to do

Oh love is oh so sweet
I can't believe I called you ma
My heart was incomplete
Until you came into my life

Wow I am getting tired.. Not only did I spell the topic wrong, I cut off the first line when I cut and pasted it form notepad.

Here are my corrections:
The proper spelling of the song title is:
The Beginning (Week One)

The first line is:
Week one was lots of fun

I'll pay more attention next time.

Is it 'I can't believe I called you mine'? That's what I have always sang, so correct me if I am wrong.

yeah, its 'i can't believe i call you mine' unless matt and his mother have something groovy going on...

I've always had trouble with this line. I go back and forth between hearing 'Made out like bandits in your room' and 'Made out like bandits in Peru.' Weird.

I thought it was

'Made out like bandits in the moon'

which makes a teeny bit more sense.

The riff:  D#-E power chords repeated

B
Week one was lots of fun
                                        (riff)
We built a fort inside your room

We walked around this town
                                           (riff)
Made out like bandits in the gloom

G#m
Where have you been so long so long
                                        C#m
I've waited oh so long for you
B                 B    A      B
 I've got ta figure out
                      A                F#m       (riff)    
Just what this means and what to do

2nd verse and chorus are same as first, then guitar solo over the following chords implied by the bass and keys:
E-D-B
G-A-B

Then the riff again, then the chorus, then the song ends on E, where the riff would've been before.
