Here in Italy we got "Festivalbar" every summer where italians and international artitsts go to present their new single and it's always been the typical playback music show. (it really sucks!!)
Bon Jovi was there in 2000 with Its my life and Say it isnt so and their appearance was playback too but some italian artists every year did a live performance...this makes me doubt a bit....
I think it has something to do with the money... since they don't go there free i think a live perfomance should cost more than a playback appearance.
