I found this and decided to learn it I canť yodle, but nvm Its just too cool

The first chord is A, then he plays D (all in 5th fret bare) but other than I am clueless:(

Also, if anyone knows, what is the name of this song - or knows the lyrics, I would greatly appreciate, cos I dont speak german:P

Youtube link: http://www.youtube.com/watch?v=W-rGlAQPXhk

First chord A
Second chord E7
There is another chord D6 or D maj6

You play D on 5th string 5th fret with your first finger and then you bar 7th fret strings D G B and E with your 3rd or fourth finger.
Hope this helps
