According to May Pang, Lennon’s girlfriend and assistant during his year-long break-up with Yoko Ono in 1973-1974, May met Jurgen at the first Beatlefest in 1974. He and John were reunited soon after, in New York City, and John chose one of his photographs for the cover of his 1975 solo release of late 1950’s – early 1960’s Rock & Roll classics.
