It has since been recorded by dozens of artists, including Dion in 1968, Clannad with Paul Young in 1991, and Mitchell herself, who re-recorded the song with an orchestral arrangement on her 2000 album Both Sides Now.
I put down the book, looked out the window and saw clouds too, and I immediately started writing the song.
This suggests that Mitchell wrote the song before 1967 (the year of composition cited in the Los Angeles Times article above) and precedes the first Judy Collins release in 1967.
[5] In April 2000, two months after the album's release, Mitchell sang the song with a 70-piece orchestra at the end of an all-star celebration for her at the Hammerstein Ballroom in New York City.
[12] Shortly after Mitchell wrote the song, Judy Collins recorded the first commercially released version for her 1967 Wildflowers album.
[15] The record peaked at number 3 on Billboard's Easy Listening survey and "Both Sides, Now" has become one of Collins' signature songs.
[19] The song features prominently in the season 6 finale of TV show Mad Men, and signals a moment of anagnorisis between Don Draper and his daughter Sally.
