From memory, and I'm not sure if this is the original key:

The verses are sung over E7 so I suppose it's the middle section you're looking for...........

         (Gsharp7)
It doesn't matter what you wear
         (Csharpminor)
just as long as you are there
         (Fsharpminor)
so come on, every etc, etc,
             (B7)
Everywhere around the world..........

C-flat(No, that's not part of it, that's my handle!!)
