The Wet Secrets - Secret March Chords & Tabs

Ok So here's the awesome marching anthem by the Wet Secrets. I was only able to figure 
the intro for the most part so you can just play around with the rest to try and get it.

Intro:

|-------------------------------------------|
|------------------------7-----9998887775---|
|------------------789-9---989--------------|
|---7-7-7767-7-7-99-------------------------|
[ Tab from: https://www.guitartabs.cc/tabs/t/the_wet_secrets/secret_march_btab.html ]
And thats also most of the song. You just have to play around with those notes until you 
figure out the whole song.

I think the chorus may go something like this, not sure though:

Chorus:

|------------------------------------------|
|---------------------------9998887775-----|
|------------------799999979---------------|
|---777777767777777------------------------|


well thats about it. hope you like it. Please give me some feedback on what you think 
im open to advice if I did something wrong, just comment.
