I remember the Witches Cauldron well. It was in the basement of Conrad's something or other. 1965. There was a group that played there regularly with a girl singer. They made an record or maybe an album. There was a wonderful harmonica player that sometimes played there. The name of the drummer was Gerry and I thought one of the guitarists was named Carmichael. The group once played for intermission for the Yardbirds and/or The Who (trying hard to remember here...) I remember a black man named Ram John who sang a song called "Big Bamboo", lol. Can someone help with names here?
