I think Gotthard was ok!!!!! Not that I liked it very much, but I liked it!!! I just remember the Homerun-Song now. The other songs they sang on the concert I have forgotten! But my fave BonJovi support-band was Reamonn, I saw them in Zeltweg in Austria in August 2000. (but I liked them before I saw them on the Bon Jovi concert! )
The Stereophonics were also great!!!!
