full_context: Document 1: I Dig Love: Leng draws parallels between "I Dig Love" and the Beatles' more free-form compositions of the late 1960s. Among these, Paul McCartney's "Why Don't We Do It in the Road?" exemplifies what Ian MacDonald termed in the 1990s the "long-gone let-it-all-hang-out era". In his book "Working Class Mystic", Gary Tillery identifies "I Dig Love" as one of two "All Things Must Pass" tracks (the other being "Wah-Wah") that could have been sung by John Lennon, whose style increasingly embraced provocative artistic statements following the start of his relationship with Yoko Ono in 1968. Leng also compares "I Dig Love" with "Love the One You're With", a "hymn to hedonism" by Stephen Stills, with whom Harrison worked on Doris Troy's eponymous album for Apple Records, in 1969–70.

Document 8: The Best Band You Never Heard in Your Life: The Best Band You Never Heard in Your Life is a double-disc live album by American musician Frank Zappa, released in 1991. The album was one of three to be recorded during the 1988 world tour, along with "Broadway the Hard Way" and "Make a Jazz Noise Here". Each of these three accounts of the 1988 tour has a different emphasis: "Broadway the Hard Way" mainly consists of new compositions; "Make a Jazz Noise Here" is a sampler of classic Zappa tunes, most of them instrumental; and "The Best Band..." devotes itself to covers. Some of these are unlikely (such as "Stairway to Heaven" by Led Zeppelin), while many are from Zappa's extensive back catalogue. His mid-1970s output is emphasized in the selection, but there is also some material from the Mothers of Invention's late 1960s recordings and one song ("Lonesome Cowboy Burt") from "200 Motels". It was re-issued in 1995 and 2012 along with his entire catalogue.

The live material on "Playground Psychotics" is interspersed with excerpts from taped conversations among band members whilst on tour, and the release includes three conceptual sections: "A Typical Day on the Road, Part 1", a collage of dialogue which opens the first disc; "A Typical Day on the Road, Part 2", which opens the second disc and "The True Story of 200 Motels", which appears at the end of disc two. The album also includes a live session with John Lennon and Yoko Ono, an alternate mix of which appears on Lennon's "Some Time in New York City" (1972).
