Mintz, to the best of my recollection, first came to my attention for his close ties to John Lennon and Yoko Ono throughout the 1970s and for his continued presence as a media consultant for Yoko following John's murder.
He first entered their sphere as a TV reporter for KABC Channel 7 in Los Angeles where a 1971 interview he conducted with Ono went so well - and was perceived as unusually fair - that Lennon agreed to be interviewed.
But while most people who lived through this era will remember Mintz for his Lennon-Ono connection, he was also quite an accomplished journalist, recording conversations with a who's who of the era, including Jack Nicholson, Allen Ginsberg, Mick Jagger, Salvador Dali, Dennis Hopper, Jayne Mansfield and many, many more.
