In 1965 Jackie had a relationship with Jimmy Page. She sang backing vocals on two Jimmy Page singles. She explains: "He showed up at a recording session with paint on his jeans and he was the youngest player in the room. I went over to him to play a few of my piddling cords and he when played them back to me, I was almost knocked out of the room. Even than, he was spectacular. He wanted to split from the music world because he was getting disillusioned. Jimmy wanted to go to Cornwall or the Channel Islands and sell pottery. He couldn`t stand the business, the strain and I couldn`t stand his dream of quietness so we split, but I guess he`s changed a lot since then".
"When I was recording in England I was looking for a really good acoustic player", DeShannon told recently. " I heard there was this new kid [Jimmy Page] who had been playing around a lot. So I played him my little riff, which I was very picky about. But Jimmy played it back to me, of course ten times better, and it was perfect. " Marianne Faithfull writes in her autobiography how Page, who occasionally backed up on her records, was "very dull in those days". But love or lust was in the air and Page and DeShannon, young kids let loose in the magical world of the music industry, became an item, having what Faithfull called "a very hot romance" in a an adjoining hotel room while she was on tour.
Jimmy Page and Jackie DeShannon were together for most of 1965, and she even escorted him on his first trip to America. They had a songwriter partnership, and they wrote the hits "Dream Boy" and "Down Turn Your Back on Me". Also, they wrote the hit of Marianne Faithfull, "Come and Stay with Me".
In an interview in 1977 Jimmy said about Jackie: "We got together afterwards (...) she said `I`ve got a copy of Bob Dylan`s new album if you`d like to hear it` and I said `Would I like to hear it?`"
