with a supergroup named "The Dirty Mac", consisting of Eric Clapton, Keith Richards of the Rolling Stones, Mitch Mitchell of the Jimi Hendrix Experience, and violinist Ivry Gitlis. Lennon and Ono continued with their experimental releases parallel to Lennon's activities in the Beatles, releasing Unfinished Music No. 2: Life with the Lions in May 1969. On 20 March 1969, Lennon and Ono married, and subsequently hosted their first "Bed-in for Peace" event. The event saw the new couple using press coverage of their marriage to advocate for peace. Recordings made around this time would be released as their third and final experimental album, Wedding Album. The Plastic Ono Band moniker was first used on 12 May, when Lennon and Ono participated in George Harrison's mixing session for "Jam Peace" – a jam that Harrison had recorded during a session with Apple Records artist Billy Preston. The track was subsequently titled "I Remember Jeep" and the artist credit on the EMI tape box was changed to George Harrison for inclusion on the bonus disc of his 1970 solo album All Things Must Pass. During the couple's second bed-in, held in Montreal in late May and early June 1969, Lennon, Ono and their guests recorded the Lennon-penned song "Give Peace a Chance" and Ono's "Remember Love". These were released on 4 July as a single credited to the Plastic Ono Band. It was the first single released by Lennon outside of the Beatles, with whom he was still active. Although an independent composition and release by Lennon, his Beatles writing partner Paul McCartney was still credited, as both a contractual and personal agreement of sharing credit. There is written and photographic evidence to suggest, however, that the original Plastic Ono Band was a sound and light installation set up in the Apple press office. In the 26 July 1969 edition of Disc and Music Echo, Derek Taylor, the Beatles press officer, wrote the following article: The band was made in perspex in Hoylake, in Cheshire (where Selwyn Lloyd and I were brought up separately) by an inventor I know called Charles Melling. It was Yoko's idea, with John, made to her specifications; four pieces – like John, Paul, George and Ringo, three taller and one shorter. Two rectangular, one cylindrical and a cube. One column holds a tape-recorder and amplifier, another a closed circuit TV set with live camera, a third a
