Thank you for all the help!
The verses (and information) you provided are the ones I had already found on various web sites. The interview and different version can be heard on the site mentioned by Brian (that site however has only parts of the song and the interview).
The recording is availoable on CD (I had ordered it through Amazon.de
(http://www.amazon.de/exec/obidos/ASIN/B00000ILH6/qid=1118858179/sr=2-2/ref=sr_2_11_2/302-2104590-9277645) [I can't do the "blue clicky"]
and version on that CD (= interview and song) lasts 9 mts 12 sec.
