Wings, sometimes billed as Paul McCartney and Wings, were a British rock band from 1971 to 1981, formed in London. The core members were Paul McCartney, the former Beatle, on vocals and bass, his wife Linda McCartney on keyboards, and Moody Blues alumnus Denny Laine on guitar and vocals. They were noted for their commercial successes, musical eclecticism, and frequent personnel changes. They went through three lead guitarists and four drummers; the core trio of the McCartneys and Laine, however, remained intact throughout the group's existence.

The Dirty Mac was John Lennon's temporary supergroup organized in December 1968 that featured Eric Clapton, Keith Richards, Mitch Mitchell and Lennon under the nom de plume of Winston Leg-Thigh. The band assembled for a one-off performance on the Rolling Stones' TV special titled The Rolling Stones Rock and Roll Circus. The Dirty Mac played Lennon's Beatles composition "Yer Blues" and "Whole Lotta Yoko", an extended blues improvisation in which they were joined by Lennon's then-girlfriend Yoko Ono and violinist Ivry Gitlis. The TV special, which included appearances by the Rolling Stones, the Who and Jethro Tull, among others, did not air as originally planned and was not released officially until October 1996.

The Mamas & the Papas were an American-Canadian folk rock vocal group that recorded and performed from 1965 to 1968, with a brief reunion in 1971. The group was a defining force in the music scene of the counterculture of the 1960s. Formed in New York City, the group consisted of Americans John Phillips, Cass Elliot, and Michelle Phillips, and Canadian Denny Doherty. Its sound was based on vocal harmonies arranged by John Phillips – the songwriter and leader of the group – who adapted folk to the new beat style of the early 1960s.

Badfinger were a British rock band formed in Swansea in 1961. Their best-known lineup consisted of Welshmen Pete Ham, Mike Gibbins (drums), and Englishmen Tom Evans (bass), and Joey Molland. Initially known as the Iveys, the band renamed themselves Badfinger, after the working title for the Beatles' 1967 song "With a Little Help from My Friends". From 1968 to 1973, Badfinger recorded five albums for Apple Records and toured extensively before they became embroiled in the chaos of Apple's dissolution. They are recognised for their influence on the 1970s power pop genre and are estimated to have sold 14 million records.

Derek and the Dominos were an English–American blues rock band formed in the spring of 1970 by singer-guitarist Eric Clapton, keyboardist-singer Bobby Whitlock, bassist Carl Radle and drummer Jim Gordon. All four members had previously played together in Delaney & Bonnie and Friends, during and after Clapton's brief tenure with Blind Faith. Dave Mason supplied additional lead guitar on early studio sessions and played at their first live gig. Another participant at their first session as a band was George Harrison, the recording for whose album All Things Must Pass marked the formation of Derek and the Dominos. Following the deaths of Radle in 1980, Gordon in 2023, and Whitlock in 2025, Clapton is the last surviving member of the band's official line-up.

Buffalo Springfield was a Canadian-American rock band formed in Los Angeles in 1966 by Canadians Neil Young, Bruce Palmer and Dewey Martin and Americans Stephen Stills and Richie Furay. The group, widely known for the song "For What It's Worth", released three albums and several singles from 1966 to 1968. Their music combined elements of folk music and country music with influences from the British Invasion and psychedelic rock. Like the contemporary band the Byrds, they were key to the early development of folk rock. The band took their name from a steamroller parked outside their house.

Klaatu was a Canadian rock group formed in 1973 by the duo of John Woloschuk and Dee Long. They named themselves after an ambassador, Klaatu, from an extraterrestrial confederation who visits Earth with his companion robot Gort in the film The Day the Earth Stood Still. After recording two non-charting singles, the band added drummer Terry Draper to the line-up; this trio constituted Klaatu throughout the rest of the band's recording career.
