I didn't get to see any of the major bands last year as I went on a weekday, but I know one of them was Pat Benetar. Most of the bands they have are well known and appeal to a wide audience (generally bands from the 70's and 80's). Sorry I don't remember more names! The stage is in the same place as the HHN stage, right across from Mel's in front of the lagoon, near the much debated Gory Grutesque Horror Make-Up show! It's definatly a good event no matter what night you go. It's definatly not as large in scale as HHN, but still very fun, especially since there is no extra charge.
