The Jimi Hendrix Experience in Hawaii in 1968. According to Ron Raffaelli who photographed the session, the girl on the right was called Cathy. She was going out with Hendrix at the time. The other girl on the left was Mike Jeffery’s girlfriend.
That is Kathleen Paulson in the photo. More photos by Ron Raffaelli and a more recent photo of Cathy in the comments of this post of another photo from the set.
I never experienced anything remotely as nice as this, then or now.
