At a "Dark Shadows" movie premiere party in LA the other night, Alice Cooper and his band were the house band. Alice actually has a small part in the movie, which is why his band was there. So Johnny got up on stage to jam with his friend. They ran through "No More Mr. Nice Guy", "Come Together" and "School's Out". Joe Perry and Steven Tyler jumped on stage for the last 2 tracks as well. There isn't any really good video yet but I found this one of them doing Zeppelin's "Whole Lotta Love."
