John wrote" by Ono, had Lennon reading the lyrics off a clip-board. Ono selected a song that was to be B-side of "Cold Turkey," "Don't Worry Kyoko (Mummy's Only Looking for Her Hand in the Snow)", which also had its premiere at the festival. Shortly before the band went into "Don't Worry Kyoko", Lennon announced that Ono was "gonna do her thing all over you". The band closed with an electric version of the Wedding Album track "John John (Let's Hope for Peace)", an extended experimental number consisting of her screaming the title repeatedly to the feedback of the electric guitars. Towards the end of Ono's performance, the audience began to boo and whistle, and the band departed the stage leaving their guitars and bass to resonate until Mal Evans turned off the amplifiers. With their stage remarks, Lennon and Ono linked their appearance there to their ongoing campaign for peace. Lennon went to Abbey Road Studios on 25 September 1969 to mix the album from their eight-track recordings. While at the session, Lennon finished the stereo master for the album, although he did go back on 20 October to re-do the "Don't Worry Kyoko" stereo master, removing the majority of Ono's vocals from his songs and Clapton's backing vocals. The album is technically a soundtrack recording, being part of the audio portion of the documentary film being made of the festival by D.A. Pennebaker, later released as Sweet Toronto. Lennon and Ono made a deal with Pennebaker to license their portion of the show for record, in exchange for rights to include their appearance. According to the Beatles Monthly, due to the adverse reaction to Ono's performance, Pennebaker removed the segments with Lennon and Ono after limited screenings of the film, later re-edited as Keep on Rockin. Showtime ultimately presented the performance in 1989, and the full movie appeared later on home video and DVD. Release and aftermath The album, released on the same day in both the UK and US, failed to chart in the UK but peaked at number 10 in the US. It was released to quash any bootleg versions that Lennon was sure would leak onto the market. US editions of the album wrongly stated that the album was recorded in England. The album came with a 13-month calendar that had photos, poems and songs in it, from Lennon's 1964 book In His Own Write,
