Chord/Tab song: Whatever Happened to the 80s

Donots - Whatever Happened To The 80's

This is my first almost completely tab.But I think most of it is correct.
If you listen carefully to this song playing it will be pretty easy.
The only things I don't get are the riff played by a 3rd guitar in the
2nd chorus and how to play the interlude.If you can make it out or if
(better in german,but not necessary)
(by the way:I would be happy about the bass and drum tab!)
sorry for possible grammar/spelling mistakes

- tune both(all) guitars down 1/2 step!
