There were four separate groups going by this name.
The first was the drinking club involved Alice and other members included Harry Nilsson, Micky Dolenz (the Monkees), Ringo Starr, Keith Moon, Bob Brown (AC publicist) and John Lennon. Alice was the President. Brown, the Treasurer. They used to meet in 'The Lair' which was an attic space in the Rainbow Bar & Grill in Hollywood. The idea was to be the last one standing.
"I founded the Hollwood Vampires when I managed the Rainbow in 1974. I had the plaque put up and the bought the baseball shirts with the large red 'V' It was originally formed to stop 'Groupies' taking up the few tables in the alcove for hours without buying drinks. We moved on to form a baseball team and played on sundays often at the Beverly Hills High School grounds. We even played against a brilliant Lesbian team in the SF Valley. Alice Cooper was the founder member of the baseball team which also included a young Meat Loaf who was playing in 'The Rocky Horror Show' at the Roxy."

The actual 'Lair' looks very different than it appears on the 'Prime Cuts' video. In the video, the Lair looks like a spacious room with booths. Actually, it's more of a small loft area that overlooks a dimly lit bar room. Behind the loft is a small, dark room, which supposedly has seen many a puerile act (If only those walls could speak). Also, there's a small staircase that leads up to the loft. The loft is roped-off from the public. And to the left of the steps is the sign that reads "Lair of the Hollywood Vampires. Pres.: Alice Cooper. Members: John Lennon, etc."
There is one famous story about the time the gang went over to Brian Wilson's house after an evening of a cocktail or two. I don't remember exactly what the line up was but Iggy Pop was there too. So, they all go to Wilson's house at 3:00 in the morning and they're walking in and Brian says, "Shhhhh, be very quiet, I don't want you to wake up the kids." He then turns around and starts playing the piano and sing at the top of his lungs, "Mama'a little girl loves shortin', shortin', Mama's little girl loves shortin' bread". That went on for a couple of hours. Needless to say, the kids woke up. Alice has told this story a lot of times and I think it is Iggy who relays it in a recently done documentary about Brian Wilson.

Group two was the baseball team which was formed out of the drinking club but not confined to it.
“It started as a softball team, it was Alice’s idea, and we played softball every weekend — sandlot softball. It was Alice’s idea to start a team called the Hollywood Vampires, and we would raise money for charity, going out playing other local teams, corporate teams or the local police department or fire department. Of course, they always won! We were a bunch of Hollywood weirdos, running around.”

Group four was announced in 2014 as a album/band project featuring Alice, actor Johnny Depp and Joe Perry of Aerosmith. An album of 70s covers (with some new material) was released in 2015 with a stellar array of guest artists including Paul McCartney, Dave Grohl, Brian Johnson and others.
In 2014 a documentary on the Vampires is also in the works.
