NOTE: While Bonehead is playing the basic chord progression above the
following tab in the intro and verses, Noel is playing something like
this:

   A2             C#7            D          E          D           E

Also, there is this little riff being played over the intro by a third
guitar (listen carefully and you'll hear it):

   A2             C#7            D          E          D           E

So in the intro and the verses where just the chords are listed, you could
play just the chords or play what Noel is playing above.

              Dsus2           E7                  D7    A
I'll pick you up at half past three, we'll have lasagne
A2                    C#7   D                             E

Then your friends will all go green for my lasagne
