I interviewed Denny for my school newspaper when the New Mamas and the Papas (John, Denny, Mackenzie Phillips and Spanky MacFarland) came to perform at my college here in New Jersey in 1984. I told him that I was born the day "Monday, Monday" was Number 1 (and so was their first album) in May, 1966 and that my parents had seen them in concert at Carnegie Hall later than fall (November 11, 1966). Denny said that even though the original group did only around 35 live performances, he remembered that the Carnegie Hall show was definitely one of the best shows they ever did. He also mentioned that their last show, at the Hollywood Bowl (August 18, 1967) was also amazing. I asked him why the Hollywood Bowl was their last live show and he said - and I quote - "That's where we performed our first concert together the year before with Sonny and Cher". He didn't mention anything about a second appearance at Carnegie Hall but that the group was supposed to perform in London and Paris but that didn't happen because of Cass's arrest.
I got to see Denny a few times with the new line-up as well as a few years back when he was doing "Dream a Little Dream" here in New York City in the West Village. He actually remembered me and autographed a poster from the show and we chatted awhile. I congratulated him for being inducted into the Rock and Roll Hall of Fame and that I loved his show and he couldn't have been more gracious.
