Go ask Alice...
“They were regulars at clubs like the Rainbow on the Sunset Strip, they formed a drinking club/softball team known as the Hollywood Vampires, whose members included Alice Cooper and Micky Dolenz, and shared a pad on the beach with Keith Moon and Ringo Starr.”
Yeah I spotted that, wondered if you knew about Alice and the Hollywood Vampires.
As for Nilsson, I just never did see the appeal of his music. I’d compare him unfavorably to Donovan from the same era.
