She has made numerous appearances as a keynote speaker at universities, museums and other institutions, talking about Cohen and writing his biography. The book itself has been published in more than 20 languages: Brazilian Portuguese, Chinese, Croatian, Czech, Danish, Dutch, Finnish, French, French-Canadian, German, Hebrew, Hungarian, Italian, Korean, Norwegian, Polish, Portuguese, Serbian, Slovenian, Spanish, Turkish, Taiwanese, with more translations underway. In March 2014 the audiobook edition won an Audiofile Earphones Award. In 2017 a French-language version of the audiobook was released. In 2017, a year after Cohen passed away, Simmons wrote another chapter for her book, picking up where the original book stopped - a conversation with Leonard on the balcony of his L.A home - and telling the story of his life and work from 2012 up to his end. The new updated edition was published in the UK and Canada and Spain and in the more recent translated editions. In 2017, Simmons was invited to the "Museum of Contemporary Ar"t in Montreal be keynote speaker and a panelist at a major exhibition dedicated to Leonard Cohen "Une Breche en Toute Chose/A Crack in Everything". She was interviewed onstage by Eleanor Wachtel for the prestigious CBC cultural radio program "Writers & Company". Simmons wrote an essay on Cohen for the exhibition's catalog, the hardback book "Leonard Cohen: A Crack In Everything"   In 2018 the Leonard Cohen exhibition went on tour, making its first stop at the "Jewish Museum of New York", and Simmons did an event there. Later the same year, when the exhibition moved to Copenhagen, Denmark, Simmons was the keynote speaker and hosted a Masterclass in writing biography. When she was in her fifties, Simmons came out as a singer-songwriter. In interviews she said that performing Leonard Cohen songs on her book tour cured her of the stage fright that put a stop to her being a singer in her youth, and had led to her decision to write about music instead. She started featuring her own songs in concerts, continuing to accompany herself on a ukulele. She recorded her debut album, "Sylvie", at" Wavelab Studio" in Tucson, AZ, produced by "Howe Gelb" of "Giant Sand". Gelb had been an early supporter of her songs and encouraged her to make a record. The record label "Light In The Attic Records" asked to release it, making Simmons the first artist to release their debut on the label.
